Questions
A particle moving with velocity is acted by three forces shown by the vector triangle PQR. The velocity of the particle will
a
change according to the smallest force QR→
b
increase
c
decrease
d
remain constant
detailed solution
Correct option is D
As per triangle law, F→1+F→2+F→3=0 i.e., net force on the particle is zero. So, acceleration is also zero. Hence velocity of the particle will remain constant.Talk to our academic expert!
