24 hrs r up......full time analysis phyx P12

[intel1993]

wavelength was 5.4 sumethings answer was B..........
Displacement time graph for ball was A
glider movement answer was D
Maximum force repulsion due to electric field was D
visible spectrum order 10^14
measurements question was D.........
FOrce with which trolley moves was 4.8 N.........

 

[Gooners]

yaaa it was C 2vt/g i thnk

its D (2v/gt) cuz horizontal distance is vt...veritcal distance is 1/2 gt^2...so it 2vt/gt^2 , t and t cancel out resulting in 2v/gt

It was D for sure.........

i did by the same methd!

Bro in the repulsive type Q, why not B?

 

[grumpy]

its

 

[grumpy]

its B i am dead sure of it.
replusive forces.
and for decresing electric strength
voltage always have the upper edge gnoomers.

its Gooners....nt gnoomers!!! Lol. :lol:

I too wrote B fr repulsive Q!

As fr Electric field strength the Q stated that hw to decrease that EFS.......
as the frmula = E= V/D ,,,,,,, question stated that the V was low thus by frmula the D incres slightly the E decreases as the voltage was comparitively low hnce any slight change in D wd have mattered..... The option regarding voltage was to increase the voltage !!!! Which also increases the E....

yea basically the naswer was from B or D..........bt i think we have to find the greatest reulsion in the uniform field which was only present in C and D hence answer was D>.....................
may b em wrong

what about the Electric field strength Q discused abov......
Nd also please tell wat did u choose about the matress Q which had springs

[intel1993]

i forgot the elctric field question hence o idea wat i did..........
n for the spring mattress it was B..............

 

[grumpy]

thats the answer gooners sorry i am wrong to spell you
vlotage was low so ig you increase the resistance pd across the plates will be low too.
for high voltages the difference is very small.
for electic field strength it says increasing replusion not constand greatest replusinon

 

[intel1993]

the question was in which uniform field while taking the charge from X to Y will produce greatest repulsion..........................
UNiform field refers to the field between the plates which were only in C and D......

1 more mark ..is gone

 

[beststriker]

what abt the ratio of pressures..i got A which was 2/1

 

[intel1993]

yea u got it rite it was A...............

 

[hassam]

The answer of the dispalcement time graph is A and that is almost 90% confirmed. I got the force 4.8N and i think its right because tension will be in both the strings.hey guyzz what about that question in which we have to estimate the frequency of visible spectrum???

guys but it was just one rubber band....so isnt tension supposed to be same throughout.....thats a valid point i guess

 

[hassam]

yea @2v/gt

 

[fznkd123]

EVERYBODY FORGOT TO DISCUSS THE force wala ques the one in wich there was a rod and the 2 angles were 30 and 90 what was the force

 

[mrpaudel]

what about the question about the resistance and length? you had to work out the new resistance of the wire? i got 2R...

its 4R for sure..!!

 

[mrpaudel]

mrpaudel B was nt possible i think. however it cud ve been C or D as the field lines moving from high to low potential.

for the field question....ok here's a logic of mine..!! u can jus eliminate A and C..coz the +vely charge particle doesnot experience repulsive force...now B and D experiences repulsion...so since B was radially outward..and D was uniform..i thought there would b same repulsion everywhere in D...so wrote B...!!
