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 = (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

When a force vector vecF=(hati+2hatj+hatk) N acts on a body and produces a displacement of vecS=(4hati+hatj+7hatk) m, then the work done is

A force vecF=6hati+2hatj+3hatk acts on a particle and produces a displacement of vecS=2hati-3hatj+xhatk . If the work done is zero, the value of x is

A force vecF=6hati+2hatj-3hatk acts on a particle and produces a displacement of vecs=2hati-3hatj+xhatk . If the work done is zero, the value of x is

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= (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 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 :
