Question

An object is said to be in equilibrium when:
1. there is no net force acting on the object
2. the total clockwise moments about any point is equal to the total anti-clockwise moments about the same point
3. the object moves with constant velocity
  1. 1 only
  2. 2 only
  3. 1 and 2 only
  4. 1,2 and 3

A
1 and 2 only
B
1,2 and 3
C

D
2 only
Solution
Verified by Toppr

A body is said to be in equilibrium if it in translational equilibrium as well as rotational equilibrium.
For translational equilibrium, net force acting on the body must be zero i.e. Fnet=0
For rotational equilibrium, net torque acting on the body must also be zero or in other words, total clockwise moments about any point is equal to the total anti-clockwise moments about the same point.
