Surface subtends a solid angle of pi on a point charge +q. Electric flux due to point charge, associated with the given surface, is

A charge of 12 muC is kept inside a closed surface. What is the flux flowing through a portion of the surface, which subtends a solid angle of pi at the point where are charge is situated?

The luminous intensity of a small plane source of light along the forward normal is 160 candela. Assume the source to be perfectly diffused, find the luminous flux emitted into a cone of solid angle 0.02 sr around a line making an angle of 60^@ with the forward normal.

A small plane source of light has illuminating power of 150 cd along the direction of forward normal. If the source is perfectly diffused, find the luminous flux emitted into a cone of solid angle 0.02 sr around a line making an angle of 60^(@) with the forward normal.

The angle of contact between liquid and solid does not depend upon

The unit of solid angle is steradian. What is the dimensional formula for steradian?

The bond length and bond angles in molecules in the solid state are calculated by:
