If the Earth losses its gravity, then for a body
Weight becomes zero, but not the mass
Mass becomes zero, but not the weight
Both mass and weight become zero
Neither mass nor weight become zero
Write the equation of acceleration which is used for height $h < \,< R_e$ from the surface of earth.
At a height of $10 \,km$ above the surface of earth, the value of acceleration due to gravity is the same as that of a particular depth below the surface of earth. Assuming uniform mass density for the earth, the depth is ............. $km$
At what distance above and below the surface of the earth a body will have same weight, (take radius of earth as $R$.)
If the earth suddenly shrinks (without changing mass) to half of its present radius, the acceleration due to gravity will be
Mass of moon is $7.34 \times {10^{22}}\,kg$. If the acceleration due to gravity on the moon is $1.4\,m/{s^2}$, the radius of the moon is $(G = 6.667 \times {10^{ - 11}}\,N{m^2}/k{g^2})$
