A) increases
B) decreases
C) becomes double
D) does not change
Correct Answer: B
Solution :
The acceleration due to gravity at the equator is given by \[g=g-{{R}_{e}}{{\omega }^{2}}\] According to the question, the rotational speed or angular velocity is increased and so, the amount of\[{{R}_{e}}{{\omega }^{2}}\]will increase. Therefore, the acceleration due to gravity (g) on equator will decrease which will cause the weight of body to decrease.
