A body displaced from `(1,1)` to `(2,2)` along the line `y=x` under the force `vecF=xhat(j)+yhat(i)` then find the work done by this force for above displacement. (all units are in S.I.)

A

`2` unit

B

`3` unit

C

`4` unit

D

`5` unit

Text Solution

Verified by Experts

The correct Answer is:
A

`W=intvec(F).dvec(r)=int_1^2F_(x)dx+int_1^2F_(y)dy`
`:'x=y:.W=int_1^2xdx+int_1^2ydy=3`
