Two point masses are located a distance, d, apart. the gravitational force of attraction between them can be quadrupled by changing the distance to. a d/2 b.2d c. d/4 d.4d

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
