Kinematics Question 8

Question: A particle is simultaneously acted by two forces equal to 4 N and 3 N. The net force on the particle is [CPMT 1979]

Options:

A) 7 N

B) 5 N

C) 1 N

D) Between 1 N and 7 N

Show Answer

Answer:

Correct Answer: D

Solution:

If two vectors $ \vec{A} $ and $ \vec{B} $ are given then the resultant

$ {R _{max}} $ = $ A+B=7N $ and $ {R _{\min }}=4-3=1N $

i.e. net force on the particle is between 1 N and 7 N.
