A force `( 3 hati +4 hat j)` newton acts on a body and displaces it by `(3 hat I + 4 hat j)` metere. The work done by the force is y Joules. Find y.

A force of (3i + 4j) Newton acts on a body and displaces it by (3i + 4j) m. The 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

If vec F =2 hat i + 3hat j +4hat k acts on a body and displaces it by vec S =3 hat i + 2hat j + 5 hat k , then the work done by the force is

A force vecF=hat i+5 hat j+7 hat k acts on a particle and displaces it throught vec s=6 hat I +9 hat k . Calculate the work done if the force is in newton and displacement in metre. (ii) Find the work done by force vec F=2hat i-3 hat j+hatk when its point of application moves from the point A(1,2,-3) to the point B (2,0, -5).

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 constant force (2 hat i+ 3 hat j+ 4 hat k) mewton pewton produces a desplacement of (2 hati +3 hat j+ 4 hat k) metre. What is the word done?

A particle acted on by two forces 4 hat i+ 3 hat j and 3 hat i+ 2 hat j is displaced from the point hat i+ 2 hat j to 5 hat i+ 4 hat j . Find the totral work done by these forces.

A particle is acted upon by the forces vec F_(1)= hati + 2hat j+ 3 hat k , vecF_(2)= 2 hat i + hat j - 3 hatk , vecF_(3) = 3 hat i - 4 hatj + 2 hat k, is displaced from the point (-2, 1, 3) to the point (1, lambda, -2 ) . If the total work done by the forces is 8. Find the value of lambda .
