Question

A body is said to be in static equilibrium when it is

• A. in the state of rest
• B. moving along a circular path
• C. accelerated by external force
• D. moving with uniform velocity

Answer 1

The correct option is A

in the state of rest

When a body remains in a state of rest under the influence of several forces, the body is in static equilibrium. A book lying on a table is in static equilibrium as the weight of the book exerted on the table vertically downwards is balanced by the equal and opposite force of reaction exerted by the table on the book vertically upwards.
