A particle moves in a straight line with retardation proportional to its displacement. Its loss of kinetic energy for any displacement 
is proportional to
A
x 2
B
e x
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
This condition is applicable for simple harmonic motion. As particle moves from mean position to extreme position its potential energy increases according to expression 
and accordingly kinetic energy decreases.
