The energy possessed by a body due to its position or configuration is called MCQ with Answer and Explanation

Explanation:
T ∝ 1/√g. If g' = 4g, T' = T/√4 = T/2. Higher gravity ⇒ faster oscillations. Memory aid: 'Pendulum: T ∝ 1/√g; 4× gravity ⇒ half period'. Oscillations proportionality frequently tested in competitive exams.

Explanation:
a' = (F/2)/(2m) = F/(4m) = a/4.

Explanation:
Minimum deviation δ_m for a prism: n = sin[(A + δ_m)/2] / sin(A/2), where A is prism angle, n refractive index. Thus δ_m depends on both A and n. Since n varies with wavelength (dispersion), δ_m also depends on wavelength, but the primary dependencies are A and n. Memory tip: 'δ_m increases with A and n; used to measure n'. This optics formula application is frequently tested in competitive exams. Always recall that minimum deviation occurs when ray passes symmetrically through prism, a key condition for derivation.
