Question

the radius of the moon is one - fourth and its mass is one eighty-first of the earth.if the acceleration due gravity o the earth surface is 9.8 m/s².what is the value on the moon' surface

Answer 1

we already know that weight on the earth is 1/6 on moon

if a mass m has weight 9.8m on earth

then on moon it will = am6

here a is acceleration on moon

then am6= 9.8m

or a6=9.8

or a = 1.62 m/s^2
