A force`F=(3thati + 5hatj)N` acts on a body due to which its displacement varies as `S=(2t^(2)hat-5hatj)m`. Work done by these force in `2 s` is .

A force vec F = (3t hat i + 5 hat j)N acts on a body due to which its position varies as vec S =(2t^2 hat i - 5 hat j) . Work done by this force in initial 2s is:

A force vecF=(5hati+4hatj)N acts on a body and produces a displacement vecS=(6hati-5hatj+3hatk) m. The work done will be

A force vecF=5hati+6hatj+4hatk acting on a body, produces a displacement vecS=6hati-5hatk . Work done by the force is

A force vecF = (5 hati + 4 hatj)N acts on a body and produces a displacement vecs = (6 hati - 5 hatj + 3 hatk)m . The work done will be

A force vecF= (3hati+4hatj) N acts on a body and displaces it by vecS= (3hati+4hatj)m . The work done (W= vecF*vecS ) by the force is :

A force vecF=(7hati+6hatj)N acting on a body, produces a displacement vecs=(6vecj+5veck )m. Work done by the force is

A force (3 hat(i)+4 hat(j)) acts on a body and displaces it by (3 hat(i)+4 hat(j))m . The work done by the force is

A force (3hati+4hatj) newton acts on a boby and displaces it by (2hati+3hatj) metre. The work done by the force is

A force vecF=5hati+6hatj-4hatk acting on a body, produces a displacement vecs=6veci+5veck . Work done by the force is
