Question

Assertion (A): A small metal ball is charged to a potential of +1 V. It is introduced into a large hollow metal sphere charged to a potential of +10,000 V and comes into contact with the inside surface of the sphere. The ball’s charge passes to the sphere completely.

Reason (R): Positive charge flows from a body at lower potential to another body at higher potential.

Since conducting shells come in contact they have same potential hence will flow to outer shell.

Solution

1 If both A and R are true and R is correct explanation of A

2 If both A and R are true but R is not the correct explanation of A

3 If A is true but R is false

4 If both A and R are false
