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 a force (2hat(i) - hat(j) + 5hat(k)) when it displaces the body from a point (3,4,-6) to a point (7,2,5) is

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

A particle acted on by constant forces 8hat(i)+2hat(j)-6hat(k)and6hat(i)+2hat(j)-2hat(k) is displaced from the point (1,2,3) to the point (5,4,1). Find the total work done by the forces.

A particle acted on forces vec F_(1)= 3 hati -hat j+ 3 hat k and vecF_(2)= 2 hat i + 3 hat j - 4 hatk , is displaced from the point (3, -2, -1) to the point (1, 5,-2) . Find the total work done by the forces.

A particle being acted upon by the forces 5hat(i)-2hat(j)+hat(k) and 3hat(i)+hat(j)-2hat(k) is displaced from the point (2,3,5) to the point (7,-2,4) . The work done by the forces is equal to

A force bar F = (3hat i-4 hat j +b hat k)N is acting on the particle which is moving from point A ( 0-1, 1) m to the point B(2, 2 3) m If net work done by the force on the particle is zero then value of b is

A force vec(F) = (4hat(i) - 3hat(j) - 5hat(k)) N moves a body for (3hat(i) + 6hat(j) + 3hat(k)) m to (ahat(i) - 8hat(j) + 5hat(k)) m. If the work done by the force is 8j, the value of .a. is
