1)
A hollow metal sphere of radius 5 cm is charged such that the potential on its surface is 10 V. The potential at the centre of the sphere is
Zero
10 V
Same as at a point 5 cm away from the surface
Same as at a point 10 cm away from the surface
2)
What happens when we separate insulated copper spheres of radii 10 cm and 15 cm, having equal charges which are initially connected by a copper wire?
Both spheres will have the same charge
Charges on 10 cm sphere will be greater than that on 15 cm sphere
Charges on 15 cm sphere will be greater than that on 10 cm sphere
Charges on both sphere become zero
3)
The force of attraction between two charged spheres separated by a distance ‘r’ is proportional to
r²
1/r
r³
1/r²
4)
The electric field intensity inside a charged conducting hollow sphere is
Zero
Inversely proportional to square of its radius
Directly proportional to its radius
Infinity
5)
Charge density of an irregular shaped conductor is
Constant
Infinity
A dimensional quantity
Different at different points
6)
Van de Graaff generator is based on
Coulomb’s law
Phenomenon of corona discharge
Charge always resides on outer surface of the conductor
Both ‘b’ and ‘c’
