If the speed of a given charged particle...

If the speed of a given charged particle moving on a circular path in a given magnetic field is doubled then the particle starts moving on a circular path of double radius.

Text Solution

Verified by Experts

The correct Answer is:
True
`r = (mv)/(qB)` and hence `r/v = m/(qB)= a` a constant for a given charge moving in a given magneitc field.
