Question

find the acceleration of the particle placed on the surface of the earth at the equator due to earths rotation.The diameter of the earth=12800 km and it takes 24 hours for the Earth to complete one revolution about its axis..??

Answer 1

T= Time period = 24 hrs =24x3600 s     

ω = 2π /T =2π/(24x3600) rad/s     

Diameter of earth =12800 km

→ Radius R=12800/2

=6400 km

=64x105  m  

Radial acceleration = (ω)²R

= 4π²x64x105/(24x3600)² m/s² 

=0.0338 m/s²
