A force `vecF=(3xy-5z)hatj+4zhatk` is applied on a particle. The work done by the force when the particle moves from point `(0, 0, 0)` to point `(2, 4, 0)` as shown in figure.

A

`(280)/(5)` units

B

`(140)/(5)` units

C

`(232)/(5)` units

D

`(192)/(5)` units

Text Solution

Verified by Experts

The correct Answer is:

D

`z` and `x` components are useless points.
so, `dw =Fy.dy = 3xy.dy = underset(0) overset(2)int 6x^(4).dx = (192)/(5) units`.
