A glass rod rubbed with silk is used to charged a gold leaf electroscope and the leaves are observed to diverse. The electroscope thin, charged is exposed to X-rays for short period. Then, (a) the leaves will diverge further (b) the leaves will melt (c) the leaves will not be affected (d) None of the above
Electrostatics
Round 1
An electroscope is a simple device consisting of a metal ball that is attached by a conductor to two thin leaves of metal foil protected from air disturbances in a jar, as shown in the sketch. When the ball is touched by a charged body, the leaves that normally hang straight down spread apart. Why (Electroscopes are useful not only as charge detectors but also for measuring the quantity of charge: The more charge transferred to the ball, the more the leaves diverge.)
Which diagram shows the leaves of an electroscope charged negatively by induction?(A) (B) (C) (D)
