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 of (3 hati + 4 hatj) Newton acts on a body and it by (3 hati + 4 hatj)m . The work done by the force is

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