A Particle of mass 100 gm moves in a potential well given by U = 8x 2 – 4x + 400 Joule. Find its acceleration at a distance of 25 cm from equilibrium in positive direction -
Text Solution
Verified by ExpertsThe correct answer is:
C
F = 
= – (16x – 4) = 4 – 16x
At equilibrium 4 – 16x 0 = 0
and x 0 = 
m = 25 cm.
At the given position x = (25 + 25) = 50 cm.
F = 4 – 16 × .5 = –4 N.
or a = 
= – 40 m/s 2
