Question
An electron moving at right angles to a 0.10-T magnetic field experiences an acceleration of 6.0x10'5 m/s. (a) What's its speed? (b) By how much does its speed change in 1 ns?
Solution
The problem you've given is related to the physics of magnetic fields. However, there seems to be a mistake in the problem statement. The force exerted by a magnetic field on a moving charge (like an electron) is always perpendicular to the velocity of the charge. This means that a magnetic field can change the direction of the velocity of a charge, but it cannot change its speed. Therefore, the speed of the electron is not affected by the magnetic field, and we cannot calculate it based on the given information. Similarly, the speed does not change over time due to the magnetic field, so the answer to part (b) is zero.
