Answer 1

Qp - заряд протона

q=10^-8   k=9*10^9

r1=0.20    r2=0.16

A=Qp*(Ф2-Ф1)

A=Qp*k*q*(1/0.16 - 1/0.2)=............

Answer 2

Calculation of Work Done by Forces

To calculate the work done by forces when moving a proton from a point located at a distance of 16 cm from the charge to a distance of 20 cm from it, we need to consider the electric potential energy.

The work done by forces can be calculated using the formula:

Work = Change in Potential Energy

The potential energy of a point charge is given by the equation:

Potential Energy = (k * q1 * q2) / r

Where: - k is the electrostatic constant (k = 9 * 10^9 Nm^2/C^2) - q1 and q2 are the charges involved (in this case, q1 is the charge creating the field and q2 is the proton) - r is the distance between the charges

In this case, the charge creating the field has a charge of 10^8 C, and the proton has a charge of 1.6 * 10^-19 C.

Let's calculate the work done step by step:

1. Calculate the potential energy at the initial distance (16 cm = 0.16 m) from the charge:

Potential Energy_initial = (k * q1 * q2) / r_initial

2. Calculate the potential energy at the final distance (20 cm = 0.2 m) from the charge:

Potential Energy_final = (k * q1 * q2) / r_final

3. Calculate the change in potential energy:

Change in Potential Energy = Potential Energy_final - Potential Energy_initial

4. The work done by forces is equal to the change in potential energy.

Let's plug in the values and calculate the work done.

Using the given values: - Charge creating the field (q1) = 10^8 C - Proton charge (q2) = 1.6 * 10^-19 C - Initial distance (r_initial) = 0.16 m - Final distance (r_final) = 0.2 m - Electrostatic constant (k) = 9 * 10^9 Nm^2/C^2

Calculation:

1. Calculate the potential energy at the initial distance:

Potential Energy_initial = (9 * 10^9 Nm^2/C^2 * 10^8 C * 1.6 * 10^-19 C) / 0.16 m

2. Calculate the potential energy at the final distance:

Potential Energy_final = (9 * 10^9 Nm^2/C^2 * 10^8 C * 1.6 * 10^-19 C) / 0.2 m

3. Calculate the change in potential energy:

Change in Potential Energy = Potential Energy_final - Potential Energy_initial

4. The work done by forces is equal to the change in potential energy.

Please note that the exact values for the potential energy and work done cannot be determined without the specific values for the charges and distances. However, you can use the provided formulas and calculations to find the values based on the given information.
