Explain gravitational force exerted by an extended object. |
|
Answer» Solution :`implies`For the gravitational force between an extended object like earth and a point mass EQUATION `F= (Gm_1 m_2)/r^2` is not DIRECTLY applicable. `implies` Each point mass in the extended object will EXERT a force on the GIVEN point mass and these force will not all be in the same direction. To add up these forces vectorially for all the point masses in the extended object to GET the total force. `implies`This is easily done using Calculus. |
