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=(5hati+4hatj)N acts on a body and produces a displacement vecS=(6hati-5hatj+3hatk) 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 of 2 hati + 3 hatj + 4 hatk N acts on a body for 4 second and producesa displacement of (3 hati + 4 hatj + 5 hatk)m . The power used 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
