Choose the correct option for the following Assertion (A) and Reason (R).

Question

G1 Physics · Accepted Answer

In the accelerating frame, the bob experiences gravitational acceleration g and a constant pseudo-acceleration opposite the vehicle acceleration. Their vector sum is a constant effective gravity g⃗ₑ. The equilibrium direction aligns with this vector. For a small angular displacement about that direction, the restoring torque is proportional to the angular displacement. Hence the motion is SHM with ω² = |g⃗ₑ|/l. Both Assertion and Reason are true, and the Reason correctly explains the Assertion.…
