What is mean by resolving a force into rectangular components? Resolve a force. of 10 N into,two components, if it acts at an. angle 30Q with the horizontal.

In the magnetic meridian of a certain place, the horizontal component of the eath's magnetic field is 0.26G and the dip angle is 60^@ . What is the magnetic field of the earth at this location?

A mass of 5.0 kg is pulled along a horizontal plane by a force in a direction making an angle 45° with the horizontal.The body moves with uniform velocity through a distance of 10 metre. Find the work done by the force(Co-efficient of firction=0.3).

A block of mass 25 kg is raised by a 50 kg man in two different ways as shown in Fig. 5.19. What is the action on the floor by the man in the two cases? If the floor yields to a normal force of 700 N, which mode should the man adopt to lift the block without the floor yielding?

A gardener moves a lawn roller through a distance of 50 m with a force of 100N. If the force is acting at an angle of 60° to the direction of motion, find the work done.

An object thrown at a certain angle to the ground moves in a curved path and fails back to the ground.. The initial and the final points of the path of the object lie on the same horizontal line. What is the work done by the force of gravity on the object?

Two heavy spheres each of mass 100 kg and radius 0.10 m are placed 1.0 m apart on a horizontal table. What is the gravitational force and potential at the mid point of the line joining the centers of the spheres? Is an object placed at that point in equilibrium? If so, is the equilibrium stable or unstable?
