A spring scale being used to measure the weight of an object reads 17.1 N when it is used on earth. The spring stretches 4.40 cm under the load. The same object is weighed on the moon, where gravitational acceleration is
1
6
g.

Find the reading of the spring scale on the moon.

HELP PLEASE

  • Physics - ,

    mg=17.1 N =>
    mg= kx
    k=mg/x
    On the moon
    mg`=kx₁
    x₁=mg`/k =m•1.6•g•x /mg=1.6x=1.6•0.044=0.0704 m
