The potential energy function (inJ) of a particle in a region of space is given asU=2x2+3y3+2z. Herex, yandzare in meter. The magnitude ofx- component of force (inN) acting on the particle at pointP(1, 2, 3) mis:

Options:

Answer:
C
Solution:

Given U=2x2+3y3+2z

The expression for the x-component of the force can be calculated as follows: 

Fx=-∂U∂x=-4x

Hence, at the point 1, 2, 3 m, the value of the force is given by

Fx=-4×1 N=4 N
