Answer :

`(A rarr p,B rarr q,C rarr q,D rarr q)`Solution :

Due to rotation of earth, `g' = g- R omega^(2) cos^(2) phi` <br> At pole there is no effect of rotation of earth <br> As `phi = 90^(@)` <br> At equator g' will increase, if `omega` decreases <br> Further, T will increase with decrease in `omega`. <br> From Kepler's third law, r should also increase. <br> `E = -(GMm)/(2r)`, so with increase in r, E also increase.
