35) C
because electric field strength is the same at any point between the plates, so its constant

36) D
E=V/d
E=700/(5/1000)
mm to m
therefore its D and direction is always from (+) to (-)

neno:
can sum1 solve these questions:
i have the answers but i dont understand them

Q9) s= v2 sin 2theta / g    tan theta=1.25/10
 10= v2 sin (2X7.125)/ 9.8
  v2= 10/ 0.025=398.125
       v = root of 398.125= 20

Q33) D  What do you not understand here?

Q34) R=v/I
       the gradient at point C is least steep. indicates V/I is least...resistance is least
