Question

What are the forces on two charges of +0.45 C and + 1.3 C, ifthey are seperated by a distance of 3.2 m? ____N Find the force of electrical attraction between a proton andan electron that are 9.5 x10^-11 apart.__N Compare this to gravitational force between these particles.___N There is a net passage of 5.5 x 10^18 electrons by a point ina wire conductor in 0.30s. What is the current in the wire?_____A What are the forces on two charges of +0.45 C and + 1.3 C, ifthey are seperated by a distance of 3.2 m? ____N Find the force of electrical attraction between a proton andan electron that are 9.5 x10^-11 apart.__N Compare this to gravitational force between these particles.___N There is a net passage of 5.5 x 10^18 electrons by a point ina wire conductor in 0.30s.

Explanation / Answer

The coulombic force of attraction or repulsion between twocharges is given by                    F =(9.0*109N.m2/C2)(q1)(q2)/ (d2) Here q1 = +0.45 C         q2 = +1.3C          d = distancebetween the charges            = 3.2 m Substituting all the given values in the above formula weget             F = (9.0*109N.m2/C2)(0.45C)(1.3C)/ (3.2m)2                = 5.14*108N
