Q7.11: NCERT Physics - Part 1 GRAVITATION 7.11 Solution: For the above problem, the direction of the gravitational…
⚠️ Common Exam Traps & Conceptual Pitfalls
Students often assume the field inside a uniform hemisphere points to the geometric centre of the sphere, but the correct direction is towards the centre of mass, which lies at a distance $3R/8$ from the flat face along the symmetry axis. Always identify the centre of mass before assigning the field direction.
For the above problem, the direction of the gravitational intensity at an arbitrary point P is indicated by the arrow (i) d, (ii) e, (iii) f, (iv) g.
Step-by-Step Verified Solution
**Answer:** (ii) e
**Step-by-Step Explanation:**
The gravitational intensity at an arbitrary point P is directed towards the centre of the hemisphere. The arrow e indicates this direction.
