Calculate the value of two equal charges if they repel one another with a force of 10 n having 10 m distance apart in a vacuum. what would be the size of the charges if they were situated in an insulting liquid whose permittivity was ten times that of a vacuum.

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_

If a negatively charged particle is placed at rest in an electric potential field that increases in the positive x-direction, what will the particle do? a. accelerate in the positive x-direction b. remain at rest c. accelerate in the negative x-direction
