A. resistance of conductor is negligible

B. electron number density is enormous

C. electron in front are pushed by the electrons from behind

D. as the electrons drift, they dislodge large number of electrons from the bonds between the atoms

6. Two monochromatic radiations of blue and green colour of the same intensity are, in turn, incident on a photosensitive surface. Which one of the following is a correct statement?

A. Threshold frequency and photoelectric current for the blue light will be more compared to the green light.

B. Threshold frequency will be same but the current will be smaller for blue light compared to the green light.

C. Both threshold frequency and photoelectric current for blue light will be more compared to green light.

D. Threshold frequency will be less but photo electric current for blue light will be more compared to green light.

7. A composite wire is made by welding together two wires end to end. The wires are made of the same material with their diameters in the ratio of 1 : 2.

A. 58 rev/min

B. 65 rev/min

C. 72 rev/min

D. 86 rev/min
