Solution

The correct option is A The net force acting on the cart is zero.
The forces which are applied by the two horses are equal in magnitude, but they are in opposite direction. Hence, the net force on the cart is zero.

In an experiment, the two opposite ends of a cart are attached to two horses respectively. The two horses are trying to move the cart in their respective directions, but it is observed that the position of the cart does not change. What can be the possible explanation?

A horse is harnessed to a cart. If the horse tries to pull the cart, the horse must exert a force on the cart. By Newton's third law the cart must then exert an equal and opposite force on the horse. Since the two forces are equal and opposite, they must add to zero, so Newton's second law tells us that the acceleration of the system must be zero and therefore no matter how hard the horse pulls, it can never move the cart.

When a horse exerts a force on cart , the cart exerts an equal and opposite force on the horse. Then how come the horse can manage to pull the cart ?

Which of these statements are true?

(A) The horse applies a force on the cart and the cart pulls the horse back with a force equal and opposite in direction.

(B) The horse applies a force on the cart and the cart applies a force on the ground.

(D) The two forces in option A are acting on two different bodies and don’t cancel each other.

Q. A cart driver prods his horse to move forward. The horse refuses to budge and explains:
According to Newton's III Law, I am pulling the cart, with a certain force and the cart, in turn, pulls me back with an equal amount of force. As they are equal in magnitude and act in opposite directions, they cancel each other.
Do you agree with the explanation given by the horse? Support your answer with proper reasons.
