An asteroid of mass 5.7×104 kg carrying a negative charge of 14.0 μc is 190 m from a second asteroid of mass 5.5×104 kg carrying a negative charge of 15.0 μc. what is the net force the asteroids exert upon each other? (g = 6.673 x 10-11 n∙m2/kg2 and k = 9.0 x 109 n∙m2/c2.) an asteroid of mass 5.7×104 kg carrying a negative charge of 14.0 μc is 190 m from a second asteroid of mass 5.5×104 kg carrying a negative charge of 15.0 μc. what is the net force the asteroids exert upon each other?

repulsion force es  R = 5,224 10⁻³ N

Explanation:

We use Newton's second law to add forces, the elective force is repulsive because the asteroids have the same type of charge and gravitational force is always attractive.

Gravitational force

      Fg = G m1 m2 / r²

      Fg = 6,673 10⁻¹¹ 5.7 10⁴ 5.5 10⁴/190²

      Fg = 5,795 10⁻⁶ N

Electric force

     Fe = k q1 q2 / r²

     Fe = 8.99 10⁹ 14.0 10⁻⁶ 15.0 10⁻⁶ / 190²

     Fe = 5.2296 10⁻³ N

The resulting force is

     R = Fe - Fg

     R = 5.2296 10⁻³ - 5.795 10⁻⁶=  5229.6 10⁻⁶ - 5,795 10⁻⁶

     R = 5,224 10⁻³ N

this is a repulsive force and the asteroids move away from each other
