If the mass of the sun were ten times smaller and gravitational constant G were ten times larger in magnitude. Then,

Answer»

g' on the Earth will not CHANGE .
Reindrops willfall faster
Time period of a SIMPLE pendulum on the Earth would decrease
Walking on the ground would become more difficult.

Solution :`implies g_E = (GM_E)/(R_E^2)`
There will not be any any change in `g_E` due to decrease in mass of sun `g_E` doesn’t DEPEND on mas of sun .
And `g_E` depends on G.
`:. G_E prop G`
`:. (g.E)/(gE) = (G.)/G
`:.g._E = g_E xx (10G)/(G)`
`:. ` Gravitational ACCELERATION on earth increses by 10 times .
