How can one object affect the motion of another without touching it? give a specific example.

There are two types of forces

1. Physical force : in this type of forces we require direct contact between two bodies

2. Field force: here we do not requires any type of physical contact with the body

so here in this type of field force we do not required any contact but only due to field present near it the body can move

so here several examples are there

a) when a magnet is placed near a piece of iron then it will move towards the iron

b) a positively charged particle when come near another charged particle then it will get attracted or repelled.

so as per all above discussion we can say that an object can move without any direct contact

d) none of the above ( it is an axial load that is the answer).
