Answer:
Explanation:
Given
mass of box is m
speed of box is v
coefficient of friction
Box is moving at a constant speed i.e. Net Force on box is zero
i.e. Frictional Force and Force Applied are Equal
The Rate at which power is generated is
Solution
Force between pair of objects of masses 1kg and 2kg that are 1m apart is given as
here G is gravitational constant
G=
therefore,
similarly Force between pair of objects of masses 2kg each that are 1m apart is given as
or F'=2F
it means Force between pair of objects of masses 2kg each that are 1m apart is equal to twice the Force between pair of objects of masses 1kg and 2kg that are 1m
