Current flowing in conductor A is 2A and current flowing in conductor ...
The magnetic field produced around a current-carrying conductor can be calculated using Ampere's law:

B = (μ₀ * I) / (2π * r)

where B is the magnetic field, μ₀ is the permeability of free space (constant), I is the current, and r is the distance from the conductor.

For conductor A:
B_A = (μ₀ * 2A) / (2π * 10cm) = (μ₀ * 2A) / (2π * 0.1m) = (μ₀ * 2A) / (0.2πm) = (μ₀ * 10A) / (πm)

For conductor B:
B_B = (μ₀ * 4A) / (2π * 10cm) = (μ₀ * 4A) / (2π * 0.1m) = (μ₀ * 4A) / (0.2πm) = (μ₀ * 20A) / (πm)

Taking the ratio of B_A to B_B:
B_A / B_B = [(μ₀ * 10A) / (πm)] / [(μ₀ * 20A) / (πm)]
= (μ₀ * 10A) / (μ₀ * 20A)
= 10A / 20A
= 1/2

Therefore, the ratio of magnetic field produced around conductor A to the magnetic field produced around conductor B at a distance 10 cm from both the conductors is 1 : 2.

So the correct answer is b) 1 : 2.
