Question

If charge Q, is 4.0 times 10^-4 C, calculate the net forces in Gaussian surface S_ using Gaussian Law Figure 2, shows three charged particles located at the vertical of an isosceles triangle, where d = 2.00 cm and q = 7.00 mu C Calculate the total electric potential at point A. the midpoint of the base Calculate the magnitude of the electric field at point A due to *q (of the top) Calculate the total electric potential energy of the three charges Calculate the magnitude of the electric force between the two negative charges at the base An ion accelerated through a potential difference of 60 0 V has its potential energy increased 1.97 times 10^15 J. Calculate the charge on the ion. Find the speed of a proton that is accelerated from rest through a potential difference of 120 What is the magnitude of the electric field, if the cube has sides of 1.20 cm and the net flux is N m^2/C The net flux of the cube is 20 0 N m^2/C, what is the enclosed charge? Give at least three properties of an electric charge

Explanation / Answer

7)We know that,

U = qV => q = U/V

q = 1.92 x 10^-17/60 = 3.2 x 10^-19 C

Hence, q = 3.2 x 10^-19 C

8)U = qV

KE = 1/2 m v^2

from energy conservation, qV = 1/2 mv^2

v = sqrt (2 q V/m)

v = sqrt (2 x 1.6 x 10^-19 x 120/1.67 x 10^-27) = 1.52 x 10^5 m/s

Hence, v = 1.52 x 10^5 m/s

8)We know that,

phi = EA =>E = phi/A

E = phi/6x0.012^2 = 1157 x phi

E = 1157 x phi

{the value of phi is cutting from the image}
