Two identical small charged spheres of each having a mass of 3.0×10^-2 kg, hang in equilibrium as shown in figure below, the length of each string is 0.15m and each angle is 5.0°.Find the magnitude of the charge on each sphere.

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is transformed ⇒ as it changes into other forms of energy.

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
