Answer:

True

Explanation:

When a satellite is orbiting the earth, the centripetal force is balanced by the gravitational force as :

$\dfrac{GMm}{r^2}=\dfrac{mv^2}{r}$

$v=\sqrt{\dfrac{GM}{r}}$ ...........(1)

Where

M is the mass of the earth

m is the mass of the planet

From equation (1), the speed of the satellite depends only on the mass of the earth and the orbital radius.

So, If a payload of material is added until it doubles the satellite's mass, the earth's pull of gravity on this satellite will double but the satellite's orbit will not be affected. It is true.
