A spherical shape is the only one able to accommodate the increased pressure when every particle pulls towards each other, to where they are all equidistant from the center. It is also called Coulombs force or Coulombs interaction. This is why very large celestial objects are spherical; objects such as stars, planets, moons, etc., are large enough for their gravity to force their mass into a sphere. "Electrostatic force" refers to the electric force generated by stationary charges. The electrostatic force (not energy) of attraction between two oppositely charged objects is given by the equation F=(Q1Q2/d2) where =8.99109Nm2/C2, Q1 and Q2 are the charges of the two objects in Coulombs, and d is the distance separating the two objects in meters. It is because gravity and electrostatic force follow theinverse-square lawwhen two masses are separated by distance. As distance increases using the same method as before the force decreases proportional to the inverse squared. Answer (1 of 8): Like charges repel each other and unlike charges attract each other. Calculate the distance from charge q 1 to the points on the line segment joining the two charges where the electric field is zero. If both charges are like or positive and positive or negative or negative, the field lines of their respective field never coincide as they repel each other. Remember: electromagnetic fields and magnetic forces are generated when charged particles move. If the electrostatic force between two charges is 124 N.
