Question

Inside a solenoid of radius \( 0.5 \) m, the magnetic field is changing at a rate of \( 50 \times 10^{-6} \) T/s. The acceleration of an electron placed at a distance of \( 0.3 \) m from the axis of the solenoid will be:

• A. \( 23 \times 10^6 \) m/s\(^2\)
• B. \( 26 \times 10^6 \) m/s\(^2\)
• C. \( 1.3 \times 10^9 \) m/s\(^2\)
• D. \( 26 \times 10^9 \) m/s\(^2\)

Hint:

The changing magnetic field inside a solenoid induces an electric field, which exerts a force on charged particles.
