An elementary particle of mass m and charge +e is projected with velocity v at a much more massive particle of charge ze where 
What is the closest possible approach of the incident particle
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Suppose distance of closest approach is r, and according to energy conservation applied for elementary charge. Energy at the time of projection = Energy at the distance of closest approach
