Answer to Question #293155 in Physics for Mich

Question

Direction: Solve the following problems below. Show your solutions.

a. A charge of 3x10^-8 C experiences an electrostatic force of 6.0x10^-8 N. Compute the force per coulomb that the charge experiences.

b. Compute the electric field experienced by a negative test charge given the following conditions in a vacuum.

i. Source charge: -4.33x10^-12 C

ii. Distance from source charge: 2.33x10^-5 m

Answer 1

(a) the force per coulomb

$$E=F/q=\rm 6.0*10^{-8}\:N/3.0*10^{-8}\: C=2.0\; N/C$$

(b) electric field experienced by a negative test charge

$$E=kq/r^2\\ =9*10^9*4.33*10^{-12}/(2.33*10^{-5})^2\\ =7.19*10^7\:\rm N/C$$
