Determine:

a. The speed of a electron.

b. The speed of a ion.

c. The specific type of particle that has of kinetic energy when moving with a speed of .

a. The speed of a electron is.

b. The speed of a ion is.

c. The particle is an Alpha particle.

See the step by step solution

Step by Step Solution

Part (a) step 1: Given information 

We need to determine the speed of a electron.

Part (a) step 2: Simplify

Kinetic energy is . So the velocity is given as

Part (b) step 1: Given information

We need to determine the speed of a ion.

Part (b) step 2: Simplify

The kinetic energy is , and the mass of is , so the velocity is given as

Part (c) step 1: Given information 

We need to determine the specific type of particle that has of kinetic energy when moving with a speed of .

Part (c) step 2: Simplify 

Here the kinetic energy is , the velocity is . So the mass of the particle will be

As the mass of the particle matches with the alpha particle. So, the particle is an alpha particle.
