A proton (charge = +1.6 x 10⁻¹⁹ C) is placed in an electric field of strength 500 N/C. Calculate the force experienced by the proton. Assume its mass = 1.67 x 10⁻²⁷ kg.
💡 Hint: Remember to use the formula F = qE.
A cylindrical wire carrying a current of 3 A produces a magnetic field at a point 0.1 m away of size B = (μ₀I)/(2πr). Calculate B at this point and give the answer in T (Tesla).
💡 Hint: Review the magnetic field's formula around a straight wire.
