A block of mass $m$ is placed on a smooth horizontal surface. A constant force $F$ is applied at an angle $heta$ above the horizontal. If the block covers a distance $d$, the work done by the force $F$ is:

A force of $10\hat i - 3\hat j + 6\hat k$ N acts on a body of mass 100 g and displaces it from $6\hat i + 5\hat j - 3\hat k$ m to $10\hat i - 2\hat j + 7\hat k$ m. The work done is

A force of 15 N acts on an object, causing a displacement of 3 m. If the work done is 45 J, the angle between the force and displacement is:

A block of mass 2 kg is pulled up a rough inclined plane of inclination $30^\circ$ with a constant force $F$ parallel to the incline. The coefficient of kinetic friction between the block and the plane is 0.2. If the block moves with a constant speed of 2 m/s, the power delivered by the force $F$ is:

A body moves a distance of 5m along a straight line under the action of a force of 10 N. If the work done is 25 J, then the angel which the force makes with the direction of motion of the body is

A force of 1200 N acting on a stone by means of rope slides the stone through a distance of 10 m in a direction inclined at ${60^0}$ to the force. The work done by the force is [Joules].

A constant force of 10 N displaces an object by 5 m in the direction of the force. The work done is:

A book is held at a constant height above the ground. How much work is done by the person holding the book?

A particle moves from point $\vec{r_1} = (-2\hat{i} + 5\hat{j})$ m to $\vec{r_2} = (4\hat{j} + 3\hat{k})$ m when a force $\vec{F} = (4\hat{i} + 3\hat{j})$ N is applied. How much work has been done by the force?

A body constrained to move in Y direction, is subjected to a force given by ${\rm{\vec F}} = \left( { - 2\hat i + 15\hat j + 6\hat k} \right)$ N done by this force in moving the body through a distance of 10m along Y axis?
