Work done when a force `F=(hati + 2hat(j) + 3hatk) N` acting on a particle takes it from the point
`r_(1) =(hati + hatk)` the point `r_(2) =(hati -hatj + 2hatk)` is .
A. `3 J`
B. `1J`
C. `zero`
D. `2J`
`r_(1) =(hati + hatk)` the point `r_(2) =(hati -hatj + 2hatk)` is .
A. `3 J`
B. `1J`
C. `zero`
D. `2J`
Correct Answer – B
`W =F.S =F.(r_(f)-r_(i))`.
