MHT CET 2022 11th August Evening Shift | Moving Charges and Magnetism Question 31 | Physics

Two parallel conducting wires of equal length are placed distance 'd' apart, carry currents '$$\mathrm{I}_1$$' and '$$\mathrm{I}_2$$' respectively in opposite directions. The resultant magnetic field at the midpoint of the distance between both the wires is

$$\frac{\mu_0\left(I_1-I_2\right)}{\pi \mathrm{d}}$$

$$\frac{\mu_0\left(I_1+I_2\right)}{2 \pi d}$$

$$\frac{\mu_0\left(I_1-I_2\right)}{2 \pi \mathrm{d}}$$

$$\frac{\mu_0\left(I_1+I_2\right)}{\pi d}$$

An electron and a proton having the same momenta enter perpendicularly into a magnetic field. What are their trajectories in the field?

Path of the electron is more curved than that of proton

They will travel undeflected

Path of the proton is more curved than that of the electron

Both the electron and the proton will move along the same curved path but they will move in opposite directions
