Find the accelerationof the moonwith respect to the eath from the following data, Distance between the earth and the moon `=3.85xx10^5` km and the time taken by the moon to complete one revolution aroudn the earth `=27.3days

Answer

A, B, C

Explanation

Distance between earth and Moon `
`r=3.85xx10^5km`
`=3.85xx10^8`m
`T=27.3 days `
`=24xx3600xx(27.3)sec`
`2.36xx10^6sec`
v=(2pir)/T` ltbr.gt `=(2xx3.14xx3.85xx10^8)/(2.36xx10^6)`
`=1025.42 m/sec `
`a=v^2/r= ((1025.420^2)/(2.36xx10^6)`
`=0.00273 m/sec^`
`=2.73xx10^3 m/sec^2`
