Domanda 7 di 8
Two charged particles P and Q are 0.10 m apart. The charge on P is 1.50 × 10ֿ⁷ C and the charge on Q is 1.50 × 10ֿ⁷ C. Particle P experiences an electrostatic force of magnitude F because it is near to the charge on particle Q. The distance between the two particles is increased to 0.20 m. The charge on P is increased to 4.50 × 10ֿ⁷ C and the charge on Q is increased to 6.00 × 10ֿ⁷ C.
What is the magnitude of the force that particle P experiences now?
