Two charged particles separated by 50 cm attract each other with a force of 2.5 N. One particle has a charge of 243 µC. What is the sign and magnitude of the other charge? k= 8.99x109 Nm2 /C2

Red blood cells can often be charged. Consider two red blood cells with the following charges: -24.6 pC and +51.6 pC. The red blood cells are 3.58 cm apart. a) What is the magnitude of the force on each red blood cell? b) The red blood cells come into contact with each other and then are separated by 3.58 cm. What magnitude of force does each of the red blood cells now experience?
