Question

A force (2i-j) N acts on a body and displaces it from (2,3) to (6,5)m. The work done by this force is​

Answer 1

Answer:

Force=2i+j

Let the distance be d.

The difference between the two pints will be our distance.

d =5i+6j-2i-3j

d=3i+3j

If we apply force and there will be displacement then it is called work.

So ,work =force * displacement

Moreover work is a scalar quantity.

W=(2i+j).(3i+3j)

W= 6+3

W=9J

Answer 2

Answer:6joule

Explanation:Find the difference between distances, such that r - r

It will be 4i + 2j

Now: (2i-j) (4i+2j) =6joule
