<h2>Answer:</h2>

<u>The right option is </u><u>(C)They travel in a loop.</u>

<h2>Explanation:</h2>

The magnetic field lines point from the north pole to the south pole. Magnetic lines of force always forms closed loops. However, the magnetic field lines do not just end at the tip of the magnet. It is equally strong at the north pole when compared with the south pole.They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole.

How does the force of gravity exerted

givi [52]

The two forces of gravity are equal

Explanation:

We can answer this question by applying Newton's third law of motion, which states that:

"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"

In this problem, we can identify the Sun as object A and the Earth as object B. This means that the force of gravity exerted by the Sun on the Earth is the action, while the force of gravity exerted by the Earth on the Sun is the reaction: according to Newton's third law, these two forces are equal and opposite.

Therefore, the two forces of gravity are equal in magnitude, which is given by:

$F=\frac{GMm}{r^2}$
