1. A test charge of +2x10^-7 C is located 5 cm to the right of a charge of +1x10^-6 C and 10 cm to the left of a charge of -1x10^-6 C. The three charges lie on a straight line. Find the force on the test charge? 2. A charge of -2x10^-9 C in an electric fi...

1.) a charge of -2x10^-9 C in an electric field between two metal plates 4cm apart is acted upon by a force of 10^-4 N. a.) what is the strength of the field? b.) what is the potential difference between the plates? my question: how will going to solve th...

can a virtual image be projected on a screen? thanks :)
