Explanation:
the light ray leaving a medium in contrast to the entering or incident ray.
Answer: Capacitor
Explanation: A capacitor stores energy as charge in an electrical field between two conducting plates called electrodes which allows the flow of electrons between them.
Answer:
Explanation:
Point P is situated outside sphere . For a non conducting sphere , electric field outside sphere is given by the relation
E = k Q / d²
15000 = 9 x 10⁹ x Q / .5²
Q = 416.67 X 10⁻⁹
Maximum field will be when d = r ( radius )
maximum E = kQ / r²
= 9 x 10⁹ x 416.67 X 10⁻⁹ / .3²
= 41667 N / C
