A particle is displaced through `(3hati - 2hatj + 2hatk)` under the influence of a force `(-hati + hatj - 5hatk) N` . Calculate the work done.

Text Solution

Verified by Experts

We are given: `vecF = (-hati + hatj - 5hatk) and vecS =(3hati - 2hatj + 2hatk)`
We are to calculate, `W = vecF . vecS ` So `W = (-hati + hatj + 5hatk) . (3hati - 2hatj + 2hatk) = (-3-2-10) J = -15 J `
