A body remains at rest under the action of several forces. This state is called:

1. Equilibrium happens when net force and net moment are zero. 2. If the body is at rest, the state is called static (or stable) equilibrium. 3. If the body moves with constant velocity instead, it is called dynamic equilibrium. 4. The given body is at rest, so the answer is static equilibrium. _Source: Selina Concise Physics ICSE Class 10, Ch 1 'Force' (icsehelp.com chapter extract)_
