A current carrying loop is placed in a uniform magnetic field. The torque acting on the loop does not depend upon

Let A, B and C be the three points in a uniform electric field $$\text { ( } \overrightarrow{\mathrm{E}})$$ as shown. The electric potential is

For the output of the following logic circuit to be 'I', the values of inputs A and B should be respectively

In photoelectric experiment keeping the frequency of incident radiation and accelerating potential fixed, if the intensity of incident light is increased,
