If a body is charged by rubbing it, its weight:

An electric dipole is placed in a uniform electric field. The net electric force on the dipole:

Given below are four statements: 

Choose the correct option:

A point charge is brought in an electric field. The electric field at a nearby point,

An electric dipole is placed in an electric field generated by a point charge.

A proton and an electron are placed in a uniform electric field.

Choose the correct option.

A charge Q is uniformly distributed over a large plastic plate. The electric field at a point P close to the centre of the plate is 10 V/m^–1. If the plastic plate is replaced by a copper plate of the same geometrical dimensions and carrying the same charge Q, the electric field at the point P will become

1.   zero

2.   5 V m^–1 

3.   10 V m^–1

4  20 V m^–1

A metallic particle having no net charge is placed near a finite metal plate carrying a positive charge. The electric force on the particle will be

1.  towards the plate

2.  away from the plate

3.  parallel to the plate

4.  zero.

Electric charges are distributed in a small volume. The flux of the electric field through a spherical surface of radius \(10~\mathrm{cm}\) surrounding the total charge is \(25\) V-m. The flux over a concentric sphere of radius \(20\) cm will be:
1. \(25\) V-m
2. \(50\) V-m
3. \(100\) V-m
4. \(200\) V-m
