The equations 2 x minus 5 y = negative 5, 11 x minus 5 y = 15, 9 x 5 y = 5, and 14 x 5 y = negative 5 are shown on the graph below. On a coordinate plane, there are 4 lines. Green line goes through (2, 1. 5) and (0. 5, negative 2). Blue line goes through (0, 1) and (0. 5, 0). Pink line goes through (negative 1, 2), and (0, negative 1). Orange line goes through (0, 1) and (2, 1. 75). Which system of equations has a solution of approximately (â€"0. 6, 0. 8)? 2 x minus 5 y = negative 5 and 14 x 5 y = negative 5 2 x minus 5 y = negative 5 and 11 x minus 5 y = 15 11 x minus 5 y = 15 and 14 x 5 y = negative 5 11 x minus 5 y = 15 and 9 x 5 y = 5.

(a) The force between them quadruples

Explanation:

According to coulomb's law, initial force between the two charged objects is given as;

where;

k is coulomb's constant

q₁ is the charge on the first object

q₂ is the charge on the second object

r is the distance between the two objects

When the charges on both objects are doubled, then;

q₁ = 2q₁

q₂ = 2q₂

Force between the two charged objects will become

Therefore, the force between them quadruples
