Question

: Fill in the blanks in the following statements:
(A) To draw water from well we have to ______ at the rope.
(B) A charged body_______ and an uncharged body towards it.
(C) To move a loaded trolley, we have to _______ it.
(D) The north pole of a magnet________ the north pole of another magnet.

Answer 1

Hint: As we know that for any motion force is required, we can relate this with real life situations and answer. Here we can also see that questions on forces between like and unlike charges are asked.

Complete step by step answer

(a.) Water can be drawn from the well by applying a force in our direction on the rope , so that it moves from the bottom of the well to the upper side. This force which is acting on the rope is called a pull.
To draw water from well we have to ___pull___ at the rope.

(b.) The charged body causes the uncharged body to acquire some charge. This process is called induction. So, the uncharged body will accumulate opposite charge hence will be attracted by the charged one.
A charged body _attracts______ an uncharged body towards it.

(c.) If we want to move a trolley then we require an external force like push or pull.
To move a loaded trolley, we have to ___push or pull____ it.

(d.) As we know that like poles repel each other and opposite poles attract each other. So
The north pole of a magnet __repels______ the north pole of another magnet.

Additional information
There are three types of magnets – permanent magnet which never lose its magnetic property, temporary magnet who have magnetic property in the presence of magnetic field and electromagnets which exhibit magnetic properties when exposed to electric current.

Note
We need to keep in mind that magnetic poles exist in pairs and if a magnet is suspended freely in air, it always aligns to earth's north and south direction.
