JEE Main 2003 — Laws Of Motion Question with Solution
From: AIEEE 2003
Question
Three forces start acting simultaneously on a particle moving with velocity, These forces are represented in magnitude and direction by the three sides of a triangle . The particle will now move with velocity
This question includes a diagram. The text above accompanies the figure.

Correct answer
D remaining unchanged
Step-by-step explanation
As shown in the figure, the three forces are represented by the sides of a triangle taken in the same order. So the particle will be in equilibrium under the three forces.
Therefore the resultant force is zero.
We know,
0 =
Therefore acceleration will be zero.
Hence the particle velocity remains unchanged.
Therefore the resultant force is zero.
We know,
0 =
Therefore acceleration will be zero.
Hence the particle velocity remains unchanged.
