Three forces P, Q, R act along the sides BC, CA, AB oftriangle ABC, taken in order. If their resultant passes through the incentre of ∆ABC, then

The resultant of two like parallel forces is 12 N. The distance between the forces is 18 m. If one of the force is 4 N, then the distance of the resultant from thesmaller force is

The resultant of three equal like parallel forces actingat the vertices of a triangle act at its

Two parallel forces not having the same line of action form a couple if they are

Two like parallel forces P and 3P are 40 cm apart. If the direction of P is reversed, then their resultant shifts through a distance of

Two like parallel forces of 5 N and 15 N, act on a lightrod at two points A and B respectively 6 m apart. The resultant force and the distance of its point of a application from the point A are

A man carries a hammer on his shoulder and holds it at the other end of its light handle in his hand. If he changes the point of support of the handle at the shoulder and if x is the distance between his hand and the point of support, then the pressure on his shoulderis proportional to

If a couple is acting on 2 particles of mass 1 kg attached with a rigid rod of length 4 m, fixed at centre, acting at the end and the angular acceleration of system about centre is 1 rad/s², then magnitude of force is
