| Query Description: |
| Two bodies of mass 100kg and 1000kg are at a distance 1.00 mt apart at which point on the line joining them will the gravitational field intensity be zero? |
| Answer: |
|
Gravitation Field Intensity = Fgr/m Let the point be at a distance x from 100 kg where we put the test mass m kg. The net gravitational forces acting on it must be zero. Gravitational Force on test mass due to 100 kg = Gravitational force on test mass due to 1000 kg 100Gm/x2 = 1000Gm/(1-x)2 1 - 2x + x2 = 10x2 9x2 + 2x - 1 = 0 x = 0.24 m Hence, at 24 cm from 100 kg mass the gravitational field intensity will be zero.
