An electron passes through a point 2.83 cm 2.83 cm from a long straight wire as it moves at 35.5 % 35.5% of the speed of light perpendicularly toward the wire. At that moment a switch is flipped, causing a current of 17.7 A 17.7 A to flow in the wire. Find the magnitude of the electron's acceleration a a at that moment.

The magnitude of electron acceleration is

Explanation:

Given:

Distance from the wire to the field point m

Speed of electron

Current A

For finding the acceleration,

First find the magnetic field due to wire,

Where

  T

The magnetic force exerted on the electron passing through straight wire,

  N

From the newton's second law

Where mass of electron kg

So acceleration is given by,

Therefore, the magnitude of electron acceleration is

you would expect a sound wave to speed up. - b)

pe = weightxheight = 2000x1000=2,000,000joules
