From,
F=Gm1m2r2G=Fr2m1m2=M-1L3T-2If unit of length is doubled,Then
G'=M-1×(2L)3T-2=8×M-1L3T-2=8GThus, the unit of
gravitaional constant becomes 8 times It means the numerical value
has to be 1/8th of its original value so that we can get a constant
value of G

if the unit of length be doubled then the numerical value of the universal gravitation G will become???? half or double or 8 times.....????
