. A particle is moving on x -axis has potential energy
U= 2-20x+5x2 Joules along x-axis. The particle is released at x = –3. The maximum value of x will be – [ x is in meters and U is in joules]
A. 5 m
B. 3m
C. 7m
D. 8m
Best Answer
Ans : C
Since particle is released at x=-3, therefore amplitude of particle is 5.
It will be oscillated about x = 2 with an amplitude of 5.
maximum value of x will be 7.
