Physics - Gravitation Question with Solution | TestHub

Consider earth to be a sphere of radius $R_e$ rotating about its own axis with angular speed $\omega$. If $g_{\mathrm{E}}$ and $g_{\mathrm{P}}$ are the accelerations due to gravity at the equator and the poles respectively, then $\left(g_{\mathrm{P}}-g_{\mathrm{E}}\right)$ is given by $\left[\cos \left(0^{\circ }\right)=\sin \left(\frac{\pi }{2}\right)=1,\sin \left(0^{\circ }\right)=\cos \left(\frac{\pi }{2}\right)=0\right]$
