Question

Force acting on the particle moving with constant speed is
a. Always zero
b. Need not to be zero
c. Always non zero
d. Cannot be concluded

Answer 1

• Particle moving with constant speed means its acceleration is must be zero.

so, F = ma

= m × 0 = 0 .

therefore,force is also zero

option a. is correct .
