Question

Three forces starts acting simultaneously on a particle moving with velocity $\overrightarrow{v}.$ These forces are represented in magnitude and direction by the three sides of a triangle ABC (as shown). The particle will now move with velocity

• A. $\overset{\rightarrow}{v}$remaining unchanged
• B. Less than $\overset{\rightarrow}{v}$
• C. Greater than $\overset{\rightarrow}{v}$
• D. $\overset{\rightarrow}{v}$in the direction of the largest force BC

Answer 1

Answer: (A)

$\overset{\rightarrow}{v}$remaining unchanged

Answer 2

Given three forces are in equilibrium i.e. net force will be zero. It means the particle will move with same velocity.
