1. The magnitude of the electric field due to a small charged object is 12N/C at a distance of 6m from the charge. What is the field 3m away from the charge?
2. Two charged spheres, 3 cm apart, repel each other with a force of 2.4 x10^-8N. Determine the magnitude and sign of the charge on each, if one has twice the charge (of the same sign) as the other.
3. Calculate the electric field intensity midway between two negative charges of 4.3 x10^-9C and 8.6 x10^-6 that are 20cm apart. Include a diagram of the situation.
ps. Plz show your steps so I follow. Much thanks
