AIIMS 2017 Physics Cyclotron Assertion Reason Question

The assertion that a cyclotron does not accelerate electrons is true because the cyclotron is designed primarily for heavier charged particles, such as protons or ions, which can achieve significant velocities and energies. However, the reason provided—that the mass of the electron is very small—is false; while electrons have a small mass (approximately 9.11 × 10⁻³¹ kg), they can still be accelerated in a cyclotron, but the design is not optimal for them due to their low mass and high velocity, which leads to relativistic effects. Option A is incorrect because the reason does not correctly explain the assertion, while option B is incorrect for the same reason. Option D is incorrect as the assertion is true.
