1Q1.
If the outer surface of the outer sphere carries a charge of 10-9C and its inner surface carries a charge of 0C. So the net potential on the outer sphere is :
9 x 109 x 109 20
This gives potential as 45 x 106 Volts
11Q1//:V=22.5
Q2//:
The electric force will act as centripetal force
let electric field at this position is E,is given by E=mxw2/e
now P.D. across a distance dx at this position is E.dx=mxw2/e *.dx
=>P.D b/w axis and the outer surface iz mrw2/2e
Q3//:cant solving
11) its a multiple of 45 .i think ankur is right
