The work done by a force `vec F = 3 hat i -4hat j +5hat k` displaces the body from a point `(3,4,6)` to a point `(7,2,5)` is

What will be work done by a force vec(F) = 2hat(i) +2hat(j) - 4hat(k) when it moves a body from the point (2,0,-3) to (1,1,-5)

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 of (-3hat(i)-hat(j)+2hat(k)) N displaced the body from a point (4, -3, -5) m to a point (-1, 4, 3) m in a staight line. Find the work done by the force.

The work done by the force vec( F ) = 6 hat(i) + 2 hat(j) N in displacing an object from vec( r_(1)) = 3 hat(i) + 8 hat( j) to vec( r_(2)) = 5 hat( i) - 4 hat(j) m , is

Work done by a force F on a body is W = F .s, where s is the displacement of body. Given that under a force F = (2 hat I +3 hat j +4 hat k) N a body is displaced from position vector r_1 = (2 hat I +3 hat j + hat k) m to the position vector r_2 = (hat i +hat j+ hat k) m. Find the work done by this force.

A particle is acted upon by constant forces vec(F)_(1)=(2hat(i)-3hat(j)+4hat(k)) and vec(F)_(2)=(-hat(i)+2hat(j)-3hat(k)) is displaced from the point A(2,1,0) to the point B(-3,-4,2) . Find the total work done by the forces.
