What would be the change in tangential velocity of an electron, if it remains in same orbit and electronic charge is doubled ?

Explanation

To solve the problem of determining the change in tangential velocity of an electron when its charge is doubled while remaining in the same orbit, we can follow these steps:

### Step-by-Step Solution

1. **Understanding the Forces**:
- An electron revolves around a nucleus due to the electrostatic force of attraction between the negatively charged electron and the positively charged nucleus.
- The centripetal force required for the electron's circular motion is provided by this electrostatic force.
