Question

При перемещении электрического заряда Q между точками с разностью потенциалов 5В силы действуют на заряд со стороны электрического поля совершили работу 4 джоулей чему равен заряд Q

Answer 1

Дано:
Δφ = 5 В
А = 4 Дж
___________
q - ?

Решение:

Работа электрического поля по перемещению заряда:
A = q·Δφ.

Отсюда:
q = A / Δφ = 4 / 5 = 0,8 Кл

Answer 2

Calculation of Charge (Q) Given Potential Difference and Work Done

To calculate the charge (Q) given a potential difference of 5V and work done of 4 joules, we can use the formula for work done in an electric field:

Work done (W) = Q * ΔV

Where: - W is the work done in joules - Q is the charge in coulombs - ΔV is the potential difference in volts

In this case, the potential difference (ΔV) is 5V and the work done (W) is 4 joules. Plugging these values into the formula, we can solve for Q:

4 joules = Q * 5V

To find the value of Q, we divide both sides of the equation by 5V:

Q = 4 joules / 5V

Therefore, the value of Q is 0.8 coulombs.

Answer 3

Calculation of Charge (Q) Given Potential Difference and Work Done

To calculate the charge (Q) given a potential difference (V) of 5V and work done (W) of 4 joules, we can use the formula:

W = Q * V

Where: - W is the work done (in joules) - Q is the charge (in coulombs) - V is the potential difference (in volts)

Rearranging the formula, we can solve for Q:

Q = W / V

Substituting the given values, we have:

Q = 4 J / 5 V

Calculating the result:

Q = 0.8 C

Therefore, the charge (Q) is equal to 0.8 coulombs.
