AIIMS 2002 Physics Motion in Electric Fields MCQ Question
Type: MCQ-conceptual-Medium-Class 12
An electron having charge e and mass m is moving in a uniform electric field E. Its acceleration will be
A
eE/m
B
eE²/m
C
eE/m²
D
mE/e
Correct Answer
Option B
Detailed Explanation
Charge on electron = e Mass of electron = m and intensity of uniform electric field = E. Acceleration of the electron, a = Force on the electron / Mass of electron = Electric charge × electric field / Mass of electron = eE/m.
