fill in the blanks by suitable conversion of units :
(i) `5ms^(-2) = ……. Km h^(-2)`
(ii) `G = 6.67 xx 10^(-11) Nm^2 kg^(-2)`
`=….. Cm^3 s^(-2) g^(-1)`

Text Solution

Verified by Experts

`G=6.67xx10^(-11)Nm^(2)kg^(-2)`
`=6.67xx10^(-11)(kgms^(-2))(m^(2)kg^(-2))`
`=6.67xx10^(-11)kg^(-1)m^(3)s^(-2)`
`=6.67xx10^(-11)(1000g)^(-1)(100cm)^(3)(s^(-2))`
`=6.67xx10^(-11)xx(1)/(1000)xx100xx100xx100g^(-1)cm^(3)s^(-2)`
`=6.67xx10^(-8)g^(-1)cm^(3)s^(-2)`.

A rocket is fired vertically upwards with a speed of upsilon (=5 km s^(-1)) from the surface of earth. It goes up to a height h before returning to earth. At height h a body is thrown from the rocket with speed upsilon_(0) in such away so that the body becomes a satellite of earth. Let the mass of the earth, M = 6 xx 10^(24) kg , mean radius of the earth, R = 6.4 xx 10^(6)m, G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) , g = 9.8 ms^(-2) . Answer the following questions: The value of h is
