A particle moving with velocity vecv is ...

A particle moving with velocity `vecv` is acted by three forces shown by the vector triangle PQR. The velocity of the particle will

A

change according to the smallest force `vec(QR)`

B

increase

C

decrease

D

remain constant

Text Solution

Verified by Experts

The correct Answer is:
D
As per triangle law ` vecF_1 + vecF_2 + vecF_3 =0` i.e., net force on the particle is zero . So acceleration is also zero
hence velocity of the particle will remain constant.
