Two particles are separated by 0.38 m and have charges of -6.25 x 10-°Cand 2.91 x 10-9 C. Use Coulomb's law to predict the force between the particles if the distance is doubled. The equation for Coulombs’ law is Fe=kg1g2/r^2 and the constant, k, equals 9.00 x 10^9 N•m^2/C^2

Centrapedial force is the answer

Multiply the 3 dimensions, assuming it is a rectangular cuboid, to get the volume in cm³ divide mass by volume to get density in g/cm³

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.
