MHT CET 2026 Physics question
Two long straight wires are arranged parallel to each other and are kept 20 cm apart in vacuum. They carry currents of 2A and 4A respectively in the same direction. What will be the magnetic force on a length of 10 cm of either wire? ( SI units)
Answer: (D)
Solution
The force between two long parallel current-carrying wires is . Substituting SI, A, A, m and m: , so N,
