Question

A particle moves under force $F=-5(x-2{)}^3.$ Motion of the particle is

• A. Translatory
• B. Oscillatory
• C. S.H.M.
• D. All of these

Answer 1

Answer: (B)

$F=-5(x-2{)}^3$
Acceleration is negative when $(x-2)$ is positive and positive when $(x-2)$ is negative.
Hence it is an oscillatory motion about $x=2$.
