Sir,
Two point masses each equal to 1 kg attract one another with a force of 1 kg.wt. What is the distance between the 2 point masses?
I solved it in the following way:
Here F = 1 kg.wt = 9.8 Newton, m1 = m2 = 1 kg, G = 6.6 x 10^(-11) N.m^2/kg^2
F = [G(m1)(m2)]/r^2
r^2 = [G(m1)(m2)]/F
By solving I get,
r = 0.00025 cm
But the book answer is 8 cm. Please say which one is right. Here the symbol ^ represents power.
