A charge of magnitude \[3e\] and mass \[2m\] is moving in an electric field \[\overrightarrow{E}.\] The acceleration imparted to the charge is [DCE 2004]
A) \[2Ee/3m\]
B) \[3Ee/2m\]
C) \[2m/3Ee\]
D) \[3m/2Ee\]
Correct Answer:
B
Solution :
Acceleration \[a=\frac{QE}{m}=\frac{\left( 3e \right)\,E}{2m}\]
