Oh okay! Thanks!When diameter decreases, R increases, V also increases since current is constant
V=IR
That explains why D is correct

This is for the first q...Sry, the answers are in a very messed up fashion...
Since it is vaccum, a= g= 10 ms-2
u=0 a=10 t=0.5T s=?
s= ut+0.5at^2
s= 5/4(T^2)
But dont panic that there is no such option, and tht it doesnt make sense..Since it is in terms of T find s for T as well
s=5T^2
For the whole time it is 5, and for half it is 5/4...so distance is 1/4th the total! Ans: B
Hope that makes sense!!
Hehe, thank you SO much for all your help! Meant a lot
No problemss..I just hope u got to see it before the exam
How was it anywayss?
