Mass remaining constant, if the earth suddenly contracts to one third

1.	Mass remaining constant, if the earth suddenly contracts to one third of its present radius, the length of the day would be shorted byA. 8/3hB. 12hC. 8hD. 64/3 h
Answer» Correct Answer - D `(R_(1))/(R_(2))=sqrt((T_(1))/(T_(2))) therefore T_(2)=(24)/(9)=(8)/(3)h` `therefore Delta T=T_(1)-T_(2)=24-(8)/(3)=(64)/(3)`.
