A negatively charged rod is held close to the disc of a neutral gold leaf electroscope. What kind of charge is produced on the
disc
gold leaves ?

A positively charged body is brought near to bob of an uncharged gold leaf electroscope , then :

What is an electroscope ? Draw a neat diagram of gold leaf electroscope .

How do you charge a gold leaf electroscope negatively by induction?

A negatively charged disc is rotated clock-wise. What is the direction of the magnetic field at any point in the plane of the disc?

When a negatively charged ebonite rod is brought close to an uncharged electroscope, the leaves of the electroscope develop positive charge and diverge.

How can you charge gold leaf electroscope positively by conduction ?

A positively charged ball is brought close to a neutral conducting isolated sphere. The isolated sphere is grounded for an instant and then the ground connection is removed.Consider the followingstatements . STATEMENT-1 : The sphere will acquire a negative charge after this process. and STATEMENT-2 : If the sphere is kept grounded and positively charged ball is moved away, the sphere will again become neutral.

Two identical conduction spheres, one having an initial charge +Q and the other initially uncharged, are brought into contact. (a) What is the new charge on each sphere? (b) While the spheres are in contact, a positively chaged rod is moved close to one sphere, causing a redistribution of hte charges on the two spheres so the charge on hte sphere closest to the rod has a charge-Q. What is the charge to the other sphere?

When a negative charged rod is brought near, but does not touch, the initially unchanged electroscope shown below, the leaves spring apart (I) . When the electroscope is then touched with a finger, the leaves collapse (II) . When next the finger and finally the rod are removed, the leaves spring apart a second time (III) . The charge on the leaves is

If a body touching the disc of an uncharged gold leaf electroscope makes its leaves .................. we can say that body is charged.
