Question

Помогите !! срочно! через 30 мин сдавать надо..Вычислите работу сил электрического поля при перемещении заряда 7 Кл между точками с разностью потенциалов 50 В

Answer 1

считаем по формуле A=qU
умножаем 7 на 50 = 350 Джоулей 
 

Answer 2

Calculation of Work Done by Electric Field

To calculate the work done by an electric field when moving a charge between two points with a potential difference, we can use the formula:

Work (W) = Charge (Q) x Potential Difference (V)

In this case, the charge (Q) is given as 7 Coulombs (C) and the potential difference (V) is given as 50 Volts (V).

Therefore, the work done by the electric field can be calculated as:

W = 7 C x 50 V

Let's calculate the value:

W = 350 Joules (J)

So, the work done by the electric field when moving a charge of 7 C between two points with a potential difference of 50 V is 350 J.

Please note that the above calculation assumes a constant electric field and a straight-line path between the two points.
