Welcome, I am even dumb, yesterday I waste my 2 hours in 1 question, read previous 2 - 3 pages

shouldnt R be zero when current is infinite

i am so silly i was just looking at that straight line didn't even read the graph properly
and for Q14 why 100*10
where did 10 come from
I am so annoying i hope i am not disturbing you

shouldnt R be zero when current is infinite

Isme current infinite kaha hain ? zero nai hain ? ?
I am weak in Electronics ._.
Temme how is it infinite ?
I shared that pic, see... I marked the dot with red marker, Isn't it zero ._. ?

i am blind ._.
i meant shouldnt the resistance be infinite when the current is zero

c'mon i am just asking a silly question from where 10 exactly?

 

[Thought blocker]

c'mon i am just asking a silly question from where 10 exactly?

Konsa 10 ?

 

[kitkat <3 :P]

c'mon i am just asking a silly question from where 10 exactly?

i think 10 is the gravity ._.

why 10*100
if it was 20*10 it would make sense but 100 is the mass of the ruler

Hadi Murtaza Explain them asap..

i dunno sorry :'(

 

[ZaqZainab]

i dunno sorry :'(

this is what a person has done i got till 24 bu 24 from the pivot is 68 not 44
14) C; upward force = tension in string = 20 x 9.81 = 196.2N
Sum of clockwise momentum = Sum of anti-clockwise momentum
Distance d x ( 50 x 9.81) = (100-40) x ( 196.2)
490.5d = 11772
D= 24 cm from the pivot.
This could either be at the mark of 16 cm or 44 cm.
