Given below are two statements:
Statement I: Rotation of the earth shows effect on the value of acceleration due to gravity (g).
Statement II: The effect of rotation of the earth on the value of ' ' at the equator is minimum and that at the pole is maximum.
In the light of the above statements, choose the correct answer from the options given below.
Statement I: Rotation of the earth shows effect on the value of acceleration due to gravity (g).
Statement II: The effect of rotation of the earth on the value of ' ' at the equator is minimum and that at the pole is maximum.
In the light of the above statements, choose the correct answer from the options given below.
- (A)Statement I is false but Statement II is true.
- (B)Statement I is true but Statement II are false.✓ Correct
- (C)Both Statement I and Statement II are true.
- (D)Both Statement I and Statement II are false.
Answer: (B)
Solution
Statement I is true: Earth's rotation causes a centrifugal effect that reduces the effective value of g, particularly at the equator. Statement II is false: at the poles, there is no effect of rotation (), while at the equator the effect is maximum (). So the effect is maximum at the equator, not at the pole. Statement I is true but Statement II is false.
