mag.field \(B = 0.2 T\)

Magnetic force \(F = Bv q\) here \(v = speed = 0\) So, magnetic force \(= 0\)

A proton is moving parallel to a uniform electric field. The electric field accelerates the proton and increases its linear momentum to \(5.0 \times 10^{-23} kg\ x\ m/s\) from \(1.5 \times 10^{-23} m/s\) in a time of 6.3 x 10^-6 s. What is the magnitude of the electric field?
