Find the acceleration of a particle placed on the surface of the earth at the equator due to earth's rotation. The diameter of erth =12800 km andit takes 24 hour for the earth to comlete one revolution about its axis.

Text Solution

Verified by Experts

The correct Answer is:
B, C
Diameter of earth = 12800 km
Radius of earth `R=6400 km=64xx10^5` m
`T=24hr=24xx3600sec`
v=(2pir)/T`
`=(2xx3.14xx64xx10^5)/(24xx3600)`
`=465.185`
`a=v^2/R=((465.185)^2)/(64xx10^5)`
` 0.038m/sec^2`

The earth has a radius of 6400 km. The inner core of 1000 km radius is solid. Outside it, there is a region from 1000 km to a radius of 3500 km which is in molten state. Then again from 3500 km to 6400 km the earth is solid. Only longitudinal (P) waves can travel inside a liquid. Assume that the P wave has a speed of 8 kms^(-1) in solid parts and of 5 kms^(-1) in liquid parts of the earth. An earthquake occurs at some place close to the surface of the earth. Calculate the time after which it will be recorded in a seismometer at a diametrically opposite point on the earth if wave travels along diameter ?
