In Millikan oil drop experiment, a charged drop falls with a terminal velocity \(v\). If an electric field \(E\) is applied vertically upwards it moves with terminal velocity \(2v\) in upward direction. If electric field reduces to \(\frac{E}{2}\) then its terminal velocity will be:

1. \(\frac{v}{2}\)

2. \(v\)

3. \(\frac{3v}{2}\)

4. \(2v\)
