Question

A particle moving with velocity ⃗V is acted by three forces shown by the vector triangle PQR. The velocity ofthe particle will :
(1) Increase
(2) decrease
(3) remain constant
(4) change according to the smallest force ⃗QR

Answer 1

The velocity of the particle will  remain constant

Step by step explanation:

From the given,

A particle moving with velocity = $\overrightarrow{V}$

Acceleration $\overrightarrow{a}=0$

                     $\overrightarrow{F}=ma$

It will be zero.

                 $\overrightarrow{v}=remains\,constant$

Therefore, The velocity of the particle will  remain constant

Hence, correct option -3
