Question

G1 Physics · Accepted Answer

Step 1: Find the equilibrium under gravity/electric force. Step 2: For a small angular displacement, linearize the restoring torque; for a dipole τ ≈ -pEθ and for a charged pendulum use the resultant effective field. Step 3: Compare Iθ¨ + κθ = 0 to obtain ω = √(κ/I). Final: A: Will increase.
