Solving a problem in physics section 67 point 81 electr

81. Two point charges Q1 = 8 nC and Q2 = −6 nC are in vacuum at a distance of r = 30 cm from each other. Determine: 1) the field strength E1 at a point lying in the middle between the charges; 2) the tension E2 at the same point, provided that the second charge is positive.
