The elongation of a wire on the surface of the earth is 10 - 4 m . The same wire of same dimensions is elongated by 6 × 10 - 5 m on 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 )

Correct answer

0

Step-by-step solution

Change in length ∝ Force ∝ m g m g = k x = Y A l x Thus, x ∝ g Then, 10 - 4 6 × 10 - 5 = g g '   ⇒   g ' = 0 . 6 g = 6   m   s - 2
