three equal 2microfarad charges are located at the angles of an equilateral triangle whose sides are 7cm each in vacuum . detrmine the absolute electric potential at the centre of the circle ( k = 9×10⁹)

Iwould say earthquakes.

M= 700 kgvalue of g( gravity) is constant = 9.8 m/s² or 10 m/s² w = mg = 700*9.8 = 6860n or 6.680*10³ n

Gravity, from the center of mass of the box, extending downward normal force, from the floor under the box, extending upward, equal to gravity push force, acting at a point on the box, extending in the direction of motion friction, acting at any point on the box directly opposite the push, extending directly opposite to the motion
