1.	The earth (mass = 6 xx 10^(24)kg) revolves around the sun with an angular velocity of 2 xx 10^(-7)rad/s in a circular orbit of radius 1.5 xx 10^8km. The force exerted by the sun on the earth, in newton, is .........
Answer» `18 xx 10^(25)` zero `27 xx10^(39)` `36 xx10^(21)` Solution :`implies m = 6 xx 10^(24) kg ,omega = 2XX 10^(-7) ` rad/s `R = 1.5 xx 10^(11) m` Foce EXERTED by Sun on the EARTH `=F= momega^(2) R` `:. F = 6 xx 10^(24) xx (2 xx 10^(-7))^2 xx 1.5 xx 10^(11)` `= 36 xx 10^(21) N`
