Question

An electron and a proton are injected into a uniform magnetic field at right angle to its direction with the same momentum. Then

• A. electrons path isless curved than protons path
• B. protons path will be less curved than electrons
  path
• C. the paths of both will be equally curved
• D. both the trajectories will be straight

Answer 1

The correct option is C the paths of both will be equally curved

R = $\frac{mv}{QB}=\frac{P}{QB}$ [ P is same]
Q and B are same in magnitude in case of e and p their path will be equally curved
