Two satellites

A

and

B

of masses

200\,\text{kg}

and

400\,\text{kg}

are revolving round the earth at height of

600\,\text{km}

and

1600\,\text{km}

respectively. If

T_A

and

T_B

are the time periods of

A

and

B

respectively then the value of

T_B - T_A

: Given: radius of earth

= 6400\,\text{km}

, mass of earth

= 6 \times 10^{24}\,\text{kg}

. (1)

1.33 \times 10^3\,\text{s}

(2)

3.33 \times 10^2\,\text{s}

(3)

4.24 \times 10^3\,\text{s}

(4)

4.24 \times 10^2\,\text{s}
