Problem: A proton is placed in a uniform electric field of 2950 N/C.A. Calculate the magnitude of the electric force felt by the proton.(F = ? )B. Calculate the proton's acceleration.( a= ? m/s2 )C. Calculate the proton's speed after 1.40  in the field, assuming it starts from rest.   ( V= ? m/s )

FREE Expert Solution

The electric force experienced by a proton in the uniform electric field:

 F=qE

Newton's second law:

F=ma

We'll use the kinematic equation:

 vf = v0 +at
