Abstract 

The paper is an attempt to give physical explanations for the causes of electrostatic, gravitational and inertial forces. This is done by considering an electric charge, of magnitude Q, as an impregnable spherical shell, with its radial field pulling the surface, equally outwards. A stable structure, such as an electron, is maintained with constant radius a, energy En and mass m. It is proposed that the electrostatic field lines of force from adjacent charges, Q and K, are curved to give a resultant pulling force of repulsion or attraction. The electric field due to charge Q, at the location of another charge K, and the field due to K at Q, are curved, becoming slightly reduced for force of repulsion and similarly increased for force of attraction, to make for a net gravitational force of attraction. A charge Q moving at a constant velocity v bears its radial electrostatic field Eo, without distortin. But, due to the finite speed of light c, change in velocity of Q is not instantaneously communicated to all the fields. Consequently, the lateral field lines become curved, to create a reactive electric field Ea opposed to acceleration. The field Ea is supposed to act at time t, on the charge Q, to create the inertial force QEa = -m(dv/dt). For a neutral body of mass M, containing N/2 positive and N/2 negative charges, the forces add to NQEa = -M(dv/dt), thereby explaining the cause of inertia, as a force internal to a body, opposing acceleration or deceleration. An important result of the paper is the replacement of warping of four-dimensional space-time continuum surrounding a body, according the theory of general relativity, with physical curvature of electric field lines from electic charges composing a body. It is hoped to contribute in resolving some of the problems of modern physics, such as the nature of space and gravity.
