Answer:
1. Falling of raindrops on earth is also an example of non-contact force.
2. The normal force "balances" the force of gravity acting on the book. In this situation, we can say the book is experiencing a balanced force and is in a state of force equilibrium. To define this in terms of net force: Force equilibrium occurs when the net force acting on an object is zero.
3. When the comb runs through dry hair, it gets charged by friction. The molecules in the paper get polarized by the charged comb, resulting in a net force of attraction.
4. When a bar magnet is being suspended freely, the bar magnet will point to the north-south direction. ... the bar magnet will not point to a fix direction.
5. the name of force is :- applied force this is becoz force is used by bullock on ploughing the field.
