MCQ

From Newton's second law of motion, it can be inferred that

A
No force is required to move a body uniformly along straight line
B
Accelerated motion is always due to an external force
C
Inertial mass of a body is equal to force required per unit acceleration in the body
✓
All of these

✓

Answer

Correct option: D.

All of these

d
(d)

By Newton's second law

$\vec{F}=m \vec{a}$

for $(1)$ Uniform motion means body is moving with constant velocity. By $(i)$ it can be said that only for accelerated motion force is required

$(2)$ is true using $(i)$

$(3)$ Using $(i)$ $\vec{a}=\frac{\vec{F}}{m}$ so this is true
