1.	Starting from the centre of the earth having radius R, the variation of g (acceleration due to gravity) is shown by which one of the following graph ?
Answer» Solution :`implies` Inside the earth , `g((GM_e)/(R_e^3)) r (0 LT r le R_e)` `:.g prop r "" ((GM_e)/R_e) ` is CONSTANT ) outside earth `g= (GM_e)/r^2 "" (r ge R_e)` `:.g prop 1/r^2` These both SITUATION is truly SHOWN in GRAPH (D)
