Question

If P is the force acting on the body, m is the mass of the body and a is the acceleration of the body, then according to Newton's second law of motion: ____.

• A. P + m.a = 0
• B. P - m.a = 0
• C. P × m.a = 0
• D. P m.a = 0

Hint:

Think of $P = ma$ as the "active" form of the law and $P - ma = 0$ as the "equilibrium" form. Both describe the same physical reality: force and mass-acceleration are always perfectly balanced.

Answer 1

The Correct Option is B
