physics paper 1,2 ........can we discuus da papper nw?

[Fallen316]

wait. were we supposed to write the poles in the ring as well ?
i just drew lines from primary coil to secondary coil .

actually that part was of how many marks ??

 

[xxvvyy]

yep....thumb rule

 

[Fallen316]

3

they never mentioned to write the poles, but the marks were out of three so idk :/

 

[beeloooo]

than i fear that yes we had to draw the poles too

 

[Fallen316]

WE ?
didn't you draw 'em ?

 

[xxvvyy]

they mention *magnetic field lines* so obviously ve have to show it...

 

[xxvvyy]

hey how did u get 13 N for the moment

 

[Fallen316]

well , then i i'm losing 3 marks in p2 UPTIL NOW

 

[beeloooo]

hey how did u get 13 N for the moment

hahaha yr let it go now ...we all knw it was 5 N

 

[beeloooo]

well , then i i'm losing 3 marks in p2 UPTIL NOW

and p 1 ?? 40 ?? yr ur gonna increase the percentil lol XD

 

[xxvvyy]

u hve to use the thumb rule and fnd the direction of the magnetic field, and draw circular lines that cut the wire in coil two.

 

[beeloooo]

WE ?
didn't you draw 'em ?

YUP I DID i am telling it generally mate

 

[Fallen316]

and p 1 ?? 40 ?? yr ur gonna increase the percentil lol XD

p1. i'm getting 38

 

[beeloooo]

i wanna bet

HAHAHA !! well 13 N would have completely tilted the balance anticlockwise downwards !! it would have been impossible to balance it

 

[xxvvyy]

yeah let him prove it...if it was 13 N

 

[bikermicefrmars]

Wht two mistakes did you make in P1 Fallen316?

 

[Fallen316]

Wht two mistakes did you make in P1 Fallen316?

1. How is heat conducted in a metal
2. electron flow and conventional current.

 

[beeloooo]

i wanna bet

here u go !! i am explaining it !! on the right hand side the force was 4 N and distance from pivot 2 cm so the moment becomes 0.08 Nm acting downwards !! ok ?

plus i don't remember the force nd distance on the left buh i remember that the moment was 0.18 action downwards , which means that the rod would tilt 0.10 moments downwards ... to balance it we needed to bring it up by 0.10 Nm !! the force X acting upwards was 2 cm from the pivot , means 0.02 m so if the force is 5 N the moment will be 0.10 Nm and the rod would now be in equillibrium as the sum of anticlockwise moment will = clockwise moment


so now whats the reward for the bet ?? we are 4 ppl waiting hahaha !!
