Answer:
Explanation:
force acting on the particle is given as
F = k x²
small work done in displacing the particle through distance "dx" is given as
dW = F dx Cos60
dW = (0.5) k x² dx
total work done in displacing the particle from "x₁" to "x₂" is given as
W = dW
W = (0.5) k x² dx
W = (0.5) (k/3) (x³₂ - x³₁)
