Question

A ion contains 9 protons, 10 neutrons, and electrons. What is the charge of the ion? The nucleus of a type of atom contains protons and electron what is the total charge at the neutrons? What is the electric force of between charges of 3 C and -2 C by a distance of 6m? By what distance must two charges of +2C and + 2 C separated that the force between them is A 5 mc charge experiences a force of directed what is the electric field (magnitude and direction) at the location of the change? Find the force (magnitude and direction) on a -20 mc charge that the 5 mC change. A - 20 mC charge experiences a force of 55 N directed west. What is the electric field magnitude and direction at the location of the charge? north south east west If this change is removed and not replaced, what is the electric field and direction at the location is used to north south east west What is the electric field at a distance of 10 cm from 7 mC of negative charge? N/C What is the electric field at a distance f 0.3 from a nucleus containing 14 protons and 14 neutrons? N/C What is the force on a proton located in an electric field of 3400 N/C? What is the proton's acceleration? m/s^2

Explanation / Answer

Answering 4 parts:

Q.3 , F= 9x 10^9 (3x -2) /(6^2) = -1.5 x 10^9 N

Q.4 , 3.40 x 10^ 19 = 9x 10^ 9 (4) / r^2

r^2 = 10.588 x 10^ -10

r= 3.25 x 10^ -5 m appr

Q.7 E =kq/r= 9x 10^9 (7 x 10^-3) / (10 x 10^-2) = 63 x 10^ 7 N/c

Q.9 F = qE = 1.6x 10^-19 (3400) = 5.44x 10^-16 N

a= F/m= 5,44x10^ -16/ 1.67 x 10^ -27 = 3.257 x 10^ 11 m/s^2
