List of top Physics Questions on Forces asked in CUET (PG)

The dimensional formula of force is:

The moment of the couple formed by the forces \(5\hat{i}+\hat{k}\) and \(-5\hat{i}-\hat{k}\) acting at the points (9, -1, 2) and (3, -2, 1) respectively, is

In Force current analogy, stiffness constant K is analogous to__

If three forces acting on a rigid body are in equilibrium, then they must:

A truss ABC loaded at B with a force of 10 kN as shown in the figure. The force in the member AC is:

The general form of a central force is represented by \(\overrightarrow F = \frac{C}{r^n}\hat r\) (C = constant) known as Inverse Power law. 
A. The force represented by above equation will be attractive if C < 0.
