Question

С каким ускорением будет падать шарик массой 10 г с зарядом 10(-5) Кл в электрическом поле Земли? Напряжённость поля вблизи поверхности Земли 130 В/мНужно через 15 минут!)

Answer 1

mg-Fэл=ma

a=mg-E*q/m=0,01*10-130*10^-5/0,01=0,1-0,0013/0,01=0,098/0,01=9,8 -  ответ

Answer 2

Calculating the Acceleration of a Charged Ball in Earth's Electric Field

To calculate the acceleration of a charged ball with a mass of 10 g and a charge of 10^(-5) C in the electric field of the Earth, we can use the following formula:

a = F/m

Where: - a = acceleration - F = force experienced by the charged ball - m = mass of the charged ball

The force experienced by the charged ball in an electric field is given by the formula:

F = qE

Where: - F = force - q = charge of the ball - E = electric field strength

Given that the electric field strength near the surface of the Earth is 130 V/m, we can calculate the force experienced by the charged ball.

Using the formula F = qE, we can calculate the force:

F = (10^(-5) C)(130 V/m)

F = 1.3 x 10^(-3) N.

Now, we can use the formula a = F/m to calculate the acceleration of the charged ball.

a = (1.3 x 10^(-3) N) / (10 g)

a = 1.3 x 10^(-1) m/s^2.

Conclusion

The acceleration of the charged ball with a mass of 10 g and a charge of 10^(-5) C in the electric field of the Earth is 1.3 x 10^(-1) m/s^2.
