Given below are two statements: One is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A\): If we move from poles to equator, the direction of acceleration due to gravity of earth always points towards the center of earth without any variation in its magnitude. Reason \(R \): At equator, the direction of acceleration due to the gravity is towards the center of earth. In the light of above statements, choose the correct answer from the options given below
Pick an option to check your answer.
Answer & Solution
Correct Answer
(D) \(A\) is false but \(R\) is true
Step-by-step Solution
Detailed explanation
Effective acceleration due to gravity is the resultant of \(g\) and \(rw ^{2}\) whose direction and magnitude depends upon \(\theta\). Hence assertion is false.
When \(\theta=0^{\circ}\) (at equator), effective acceleration is radially inward.
