Question

Pick out the correct statement

• A. Second law of motion is a vector equation
• B. Second law of motion is applicable to a particle and not to the system of particles
• C. Force is always in the direction of motion
• D. If external force on a body is zero, it does not mean the acceleration is zero
• E. Acceleration at an instant depends on the history of the motion of the particle

Hint:

A vector equation has both magnitude and direction. Newton's second law is one of the most important vector equations in mechanics.
