A body weighs 63 N on the surface of the earth. What is the gravitational force on to the earth at a height of 3200 km from the earth's surface? (Radius of the earth is 6400
km)​

Gravitational force mg' =(49)mg=49×63=28N.

Explanation:

What is the gravitational force on it due to the Earth , at a height equal to half the radius of the Earth ? (Given that the radius of Earth = 6400 km). Gravitational force mg ( This is not the real explanation)

wavelength divides in half and speed stays the same.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
