(a) The electrostatic force (not energy) of attraction betweentwo oppositely charged objects is given by the equationF = k(Q1Q2>d2) where k = 8.99 x 109 N-m2/C2, Q1 andQ2 are the charges of the two objects in Coulombs, and d isthe distance separating the two objects in meters. What isthe electrostatic force of attraction (in Newtons) between anelectron and a proton that are separated by 1.00 x102 pm?(b) The force of gravity acting between two objects is givenby the equation F = G(m1m2>d2), where G is the gravitationalconstant, G = 6.674 x10-11N-m2/kg2, m1 and m2 arethe masses of the two objects, and d is the distance separatingthem. What is the gravitational force of attraction (inNewtons) between the electron and proton? (c) How manytimes larger is the electrostatic force of attraction?

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
