Apple falls from a tree due to gravity. State which is greater in magnitude-force exerted by earth on the apple or force exerted by apple on the earth. |
| Answer» Solution :The GRAVITATIONAL force between the earth and the apple is `F=(GMm)/R^2` ACCELERATIONOF the earth towards the apple`a=^F//_M=(GMm)/(R^2xxM)=(Gm)/R^2=(6.67xx10^(-11)xx0.25)/((6.4xx10^6)^2)THEREFORE g=4xx10^(-25)m//s^2` | |
