If a soap bubble be electrified, will its shape be changed? If so, how will the potential of the bubble change? |
|
Answer» Solution :A soap bubble is considered as a spherical conductor. When it is a electrified, the charge distribution on its surface will have a REPELLING EFFECT. HENCE, the radius of the bubble INCREASES. Capacitance of a spherical conductor varies with its radius, but it still remains spherical. So, the capacitance of the charged bubble increases. The POTENTIAL, `V= (" charge ")/(" capacitance ")`, if the charge constant, potential of the bubble will decrease. |
