A force `vec(F) = 4 hati + hatj + 3hatk` newton acts on a particle and displaces it through displacement `vec(S) = 11 hati + 11 hatj +15 hatj` metre. Calculate the work done by the force.

A force vecF=hati+2hatj+3hatkN acts on a particle and displaces it through a distances vecs=4hati+6hatjm calculate the work done.

A force (vecF) = 3 hati + c hatj + 2 hatk acting on a partical causes a displacement: (vecs) = - 4 hati + 2 hatj + 3 hatk in its own direction . If the work done is 6 j , then the value of c is

A force vecF=2hati-3hatj+7hatk(N) acts on a particle which undergoes a displacement vecr=7hati+3hatj-2hatk (M). Calculate the work done by the force

Two constat forece vecF_(1) = (2hati + 3hatj + 3hatk) newton and vecF_(2) = (5hati - 6hatj - 2hatk) newton act toghter on a particle during its displacement from the position (20hati + 15hatj) m to 8vecKm . Calculate the work done.

A force (F) = - 5 hati - 7hatj + 3hatk acting on a particles causesa displacement (s) = 3hati - 2hatj + ahatk n its own direction. If the work done is 14 J, then the vaule of 'a' is

If a force vecF=(-3hati+4hatj+2hatk) acts on a body and displaces it such that vecs=(4hati-3hatj-2hatk) then calculate the amount of work done by the force.

A force oversetrightarrowF=hati+5hatj+7hatk acts on a particle and displaces it through oversetrightarrows=6hati+9hatk . Caldulate the work done if the force is in newton and displacement in metre.

A force of vecF=(hati+2hatj+3hatk)N when acting on a particle propels it from a point (hati+hatj+hatk) to a point (hati-hatj+2hatk) . Calculate the amount of work done by the force.
