Two resistance wires of same material and same length have diameters in ratio 2:1. Their resistances are in ratio MCQ with Answer and Explanation

Explanation:
For perpendicular forces: R = √(F₁² + F₂²) = √(9 + 16) = √25 = 5 N. Pythagorean theorem applies for vector addition at 90°. Memory aid: '3-4-5 triangle for perpendicular forces'. Basic vector addition problem testing magnitude calculation, common in mechanics sections of competitive exams.

Explanation:
m1 = 5/8 = 0.625 kg, m2 = 5/24 ≈ 0.2083 kg. Total m=0.8333 kg. a = 5/0.8333 ≈ 6 m/s².

Explanation:
Outside N to S, inside S to N, forming closed loops.
