Problem

(a) Show that for a body of mass

m

, the ratio of its weights at two places A and B is equal to the ratio of the local accelerations due to gravity, that is,

\dfrac{W_A}{W_B} = \dfrac{g_A}{g_B}

. (b) A body weighs

60\,\text{N}

at place A where

g_A = 9.8\,\text{m/s}^2

. If the same body weighs

54\,\text{N}

at place B, determine the value of

g_B
