WEST-NES Physics - Free Test Sample Questions

Suppose that an object is in the rest state. What will be the direction of net acting force if 5N force acts toward its left direction and 2N force acts toward its right direction?

Correct Answer:
to the left


when analyzing the direction of the net force acting on an object, it is important to consider the magnitude and direction of all individual forces acting on that object. in this scenario, there are two forces to consider: one force of 5n acting toward the left and another force of 2n acting toward the right.

according to newton's first law of motion, an object will remain at rest or in uniform motion in a straight line unless acted upon by a net external force. in this case, the net force is determined by subtracting the smaller force from the larger force, taking into account their directions. the force acting to the left is greater than the force acting to the right (5n > 2n), so they do not cancel each other out completely.

to find the net force, we subtract the magnitude of the smaller force (2n to the right) from the magnitude of the larger force (5n to the left). this calculation is as follows: 5n (left) - 2n (right) = 3n (left). this means that the net force acting on the object is 3n toward the left.

consequently, the object will experience a net force that moves it in the direction of the greater force, which in this case is to the left. this aligns with newton's first law, indicating that the object will start moving to the left unless other forces are applied to balance this net force or alter its motion.
