Solution

The correct option is D if the net force acting on it is zero
When the net force acting on a body is zero, it is said to be in equillibrium. This means that the forces acting on it in one direction is equal to the forces acting on it in the opposite direction.

Q. Choose the correct statement(s):
Statement 1: Unbalanced forces can change the direction of motion of a body.
Statement 2: A balanced force is required to accelerate the body.
Statement 3: An object moves with a uniform velocity when balanced forces are acting on it or if there is no net force acting on it.
Statement 4: Balanced force cannot bring an object at rest to motion.

How can it be said that an object in Uniform motion is in equilibrium as it is being acted upon by a net externel force in the direction of motion? To be in equilibrium all the forces acting on it should cancel each other, right?

If the net force on an object is acting in the direction of its motion, its speed decreases.

It is stated that every action has a equal and and opoosite direction so if a body is at rest and there there is no net externel force acting on it so there are any other force acting on the body like frictional is the force acts when only a body is in motion

10) A force of 12 N and 8 N acts on a body. What would be the net force acting on it and the direction of the net force

a) if they are acting in the same direction?

b) if they are acting in the opposite directions.?
