Two persons are raising a load pulling at an angle of each other. If they exert forces of `30 N` and ` 60 N` respectively and their effective pull is at right angles to the direction of the pull of the first person, what is the angle between their pulling forces ? What is the effective pull

Tow boys raising a buket pull it at an angle theta to each ogher. If each exerts a force of 20 N and their effective pull is 30 N , what is the angle theta between their arms ?

Two forces A and B are acting at a point . The least and greatest resultants of these forces are 5 N and 10 N respectively . If each of these forces is decreased by 2 N , then what will be the resultant of these new forces acting at an angle of 30^(@) to each other ?

A boy pulls a wagon with a force of 6 N east as another boy pushes it with a force of 3 N east. What is the net force?

A child pulls a rope attached to a stone with a force of 80N . The rope makes and angle of 40^(@) to the ground. (i) Calculate the effective value of the pull tending to move the stone along the ground. (ii) Calculate the force tending to lift the stone.

In a game of tug-o-war, Mark pulls the rope with a force of 60 N from the right. Sanday and George pull the rope with respective forces of 40 N and 20 N from the left, as shown in the given figure. The net force on the rope is

Five persons A, B, C, D and E are pulling a cart of mass 100 kg on a smooth surface and the cart is moving with an acceleration of 3ms^(-2) in the east direction. If another person F comes and ans starts pulling the cart with a force of 100 N due west , then the acceleration of the cart will be
