A force of (2 hat(i) + hat(j) + 2hat(k))N is acting on a body, shifted it from (1, 2,0) to (2, 3,4) in the same frame of reference The vector component of the force along the displacement of the body

Answer»

`(5)/(sqrt6) (2 hat(i) + hat(j) + 3HAT(k))`
`(5)/(6) (hat(i) + 2hat(j)+ hat(k))`
`(11)/(18) (hat(i) + hat(j) + 4hat(k))`
`(11)/(8) (hat(i) - hat(j) + 4hat(k))`
