To calculate the kinetic energy (KE) and linear momentum (p) of a moving electron given its rest mass and the ratio of its moving mass to its rest mass, we can use the relativistic formulas. The relativistic kinetic energy formula is:

KE = (γ - 1) * mc²

where γ (gamma) is the Lorentz factor given by γ = 1 / sqrt(1 - v²/c²), m is the rest mass of the electron, and c is the speed of light.

The linear momentum (p) of the electron can be calculated using the relativistic momentum formula:

p = γ * mv

where γ (gamma) is the same Lorentz factor, m is the rest mass of the electron, and v is the velocity of the electron.

Let's substitute the given information into these formulas:

Given: Mass of moving electron (m') = 11 * Rest mass of electron (m)

Since the ratio of the moving mass to the rest mass is given as 11, we can write:

m' = 11m

Since the rest mass of an electron is approximately 9.11 × 10^(-31) kilograms, we have:

m' = 11 * 9.11 × 10^(-31) kg

Now, we can calculate the kinetic energy and linear momentum.

First, let's find the rest mass of the electron (m):

m = 9.11 × 10^(-31) kg

Next, let's calculate the moving mass of the electron (m'):

m' = 11 * m = 11 * 9.11 × 10^(-31) kg

Now, we can calculate the Lorentz factor (γ):

γ = 1 / sqrt(1 - v²/c²)

Since the velocity (v) is not given, we cannot determine the Lorentz factor, kinetic energy, and linear momentum without additional information.
