Answer 1

Newton's first law is valid only in the absence of net force. (option b)

• Newton's first law of motion is also called the law of inertia.
• It states that " A body would remain in the state of rest or motion until and unless an external force is applied."
• There is no net force seen in the objects or the body as it will remain in the state of rest and on the applied force it would be in motion.
• There is no net force required.

Answer 2
