The force with which the erth attracts a...

The force with which the erth attracts an object is called the weight of the object. Calculate the weight of the moon from the following data: The universal constant of gravitastion `G=6.67xx10^-11 N-m^2/kg^2` mass of the moon `=7.36xx10^22 ` kg, mass of the earth `=6xx10^24` kg and the distasnce between the earth and the `moon=3.8xx10^5` km.

Text Solution

Verified by Experts

The correct Answer is:
A, B
`F= (GMm)/R^2 `
` =(6.67xx10^-11xx7.36xx10^22xx6xx10^24)/93.8xx3.8xx10^16)`
` 2xx10^20 N`.
