Question

Three concurrent coplanar forces $1N$, $2N$ and $3N$ acting in different directions on a body

• A. can keep the body in equilibrium if $2N$ and $3N$ act at right angle
• B. can keep the body in equilibrium if $1N$ and $2N$ act at right angle
• C. cannot keep the body in equilibrium
• D. can keep the body in equilibrium in $1N$ and $3N$ act at aaan acute angle

Answer 1

The correct option is C

cannot keep the body in equilibrium

Given information

The magnitude of three concurrent forces$=$$1N$, $2N$ and $3N$

Draw a diagram

Explanation:

1. If $1N$ and $2N$ forces act in the same direction, $3N$ forces balance them.
2. In the question, it is stated that the three forces are pointing in separate directions, indicating that they are not in equilibrium.

Hence, the correct option is (C).
