Correct Answer

(A) Sum of resolved parts in any two directions at right angles, are both zero

[#337] If the tension in a cable supporting a lift moving upwards is twice the tension when the lift is moving downwards, the acceleration of the lift, is
Correct Answer

(B) $$frac{{ ext{g}}}{3}$$

[#338] Minimum potential energy of a system will be in the position of
Correct Answer

(A) Stable equilibrium

[#339] On a mass ‘m’ describing a circular path of radius ‘r’, the centrifugal force
Correct Answer

(C) Acts away from the centre of rotation

Explanation

Solution: The centrifugal force on a mass 'm' describing a circular path of radius 'r' acts away from the centre of rotation. It is given by the formula: F = (m * w^2 * r) / g Where: F is the centrifugal force m is the mass w is the angular velocity r is the radius of the circular path g is the acceleration due to gravity kfg is not relevant to the context and seems to be a typo or irrelevant notation in the provided options. Therefore, the correct option is: Option C: Acts away from the centre of rotation
