B
Unbalanced force
असंतुलित बल
C
Zero acceleration
शून्य त्वरण
D
Constant speed
निरंतर गति

Explanation

The book resting on the table is at rest and not moving, meaning its acceleration is zero. The forces acting on it are:

  • Gravity pulling the book downwards.
  • Normal force from the table pushing upwards.

These two forces are equal in magnitude and opposite in direction, hence balanced forces. Balanced forces result in zero acceleration and the object remains at rest or moves with constant velocity.
