If you push against a wall, the wall pushes back against you with force.
1. equal
2. less
3. more
4. no

1. Equal.

Explanation:

Newton's third law of motion;

   According to this law every action have its reaction with same magnitude but in the opposite direction.

If we push a wall with some amount of force then wall pushes back with same magnitude but in the opposite direction.This law tell us about action and reaction forces which are in same magnitude but in the opposite direction.

Therefore the answer will be 1.

1. Equal.
