Question

Two forces 12 N and 8 N act on a body of mass
24 kg. Whatever may be the direction of the
forces, the acceleration of the body cannot be
less than -​

Answer 1

1/6 the minimum possible force is when it acts opposite so net force will be 4N

4= ma

4=24*a

Or a = 1/6

Acceleration can’t be less than 1/6

Hope it helps

Answer 2

Given: Two forces 12 N and 8 N act on a body of mass 24 kg.

To find: Minimum acceleration of the body

Solution: For minimum acceleration of the body having mass 24 kg, the force acting on it should be minimum on the body.

For the force to be minimum on the body, the two forces should act opposite to each other. In this process, the magnitude of the force decreases.

Net force when 12 N and 8 N are acting opposite to each other

= 12 N - 8 N

= 4 N

Mass of the body= 24 kg

Acceleration of the body can be calculated using the formula:

Force = Mass × Acceleration

=> 4 = 24 × Acceleration

=> Acceleration = 4 N /24 kg

=> Acceleration = 1/6 m/s^2

Therefore, the acceleration of the body is option (4) 1/6 m/s^2.
