Question

Calculate the speed of the satellite in an orbit at a height of 1000000m from the Earth's surface...(Mass of the earth=5.98×10^24 kg , Radius of the earth=6.4×10^6​

Answer 1

Answer:

orbital velocity of the satellite is given as

$v = 7.34 \times 10^3 m/s$

Explanation:

As we know that the formula for the orbital speed is given as

$v = \sqrt{\frac{GM}{r}}$

here we know that

$r = R + h$

$r = 6.4 \times 10^6 + 10^6$

now we have

$v = \sqrt{\frac{(6.67 \times 10^{-11})(5.98 \times 10^{24})}{(7.4 \times 10^6)}}$

$v = 7.34 \times 10^3 m/s$
