The radius of the sphere is r=5.15 cm=0.0515 m, and its surface is given by
So the total charge on the surface of the sphere is, using the charge density
:
The electrostatic force between the sphere and the point charge is:
where
ke is the Coulomb's constant
Q is the charge on the sphere
is the point charge
r is their separation
Re-arranging the equation, we can find the separation between the sphere and the point charge:

Answer:
Maximum charge will be
Explanation:
We have given force ion the moving charge
Maximum speed of the moving charge v = 30 m /sec
Magnetic field
We have to fond the charge
Force on moving charge is given by
So
Maximum charge will be
