The elongation of a wire on the surface of the earth is10-4 m. The same wire of same dimensions is elongated by6×10-5 mon another planet. The acceleration due to gravity on the planet will be _____m s-2. (Take acceleration due to gravity on the surface of earth=10 m s-2)

Answer:
6.00
Solution:

Change in length Forcemg

mg=kx=YAlx

Thus, xg

Then, 10-46×10-5=gg'  g'=0.6g=6 m s-2
