A point mass of \(10 \mathrm{~kg}\) is placed at the centre of earth. The weight of the point mass is
- A zero
- B \(98 \mathrm{~N}\)
- C \(49 \mathrm{~N}\)
- D \(10 \mathrm{~N}\)
Answer & Solution
Correct Answer
(A) zero
Step-by-step Solution
Detailed explanation
At the centre of earth, gravitational acceleration \(g\) is zero. Hence, weight of point mass, \(w=m g=10 \times 0=0\)
