A circular plane sheet of radius 10 cm is placed in a uniform electric field of 5 x 105N C-1, making an angle of 600 with the field. The electric flux through the sheet is
A uniform electric field E = 2 x 103 N C-1 is acting along the positive x-axis. The flux of this field through a square of 10cm on a side whose plane is paralled to the yz plane is
In the above question , the flux through the same square if the line normal to its plane makes a 60° angle with the x-axis is
Which of the following statements about dipole moment is not true?
The unit of electric dipole moment is
Two charges + 20 μC and -20 μC are placed 10 mm apart. The electric field at point P, on the axis of the dipole 10 cm away from its centre O on the side of the positive charge is
Consider a region inside which, there are various types of charges but the total charge is zero. At points outside the region
Two point charges of 1μC and -1μC are separated by a distance of 100 Å. A point P is at a distance of 10 cm from the midpoint and on the perpendicular bisector of the line joining the two charges. The electric field at P will be
