Rub a plastic pen on a piece of cloth. bring it near to small pieces of paper put on table. what will you observe? use the knowledge on electrostatics to explain the phenomen b. now, instead of small pieces of paper, you have aluminum filings (small pieces aluminum) on the table. whal happens to then if you bring the rubbed plastic pen nea them? explain why

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
