(a) In steady state, no current will flow through capacitor. Applying Kirchhoff's second law in loop 1
Applying Kirchhoff's second law in loop 2
Solving Eqs. (i) and (ii), we get
(b) In position 2 : Circuit is as under
(i) Steady state current in :
(ii) Time when current in is half the steady value

(a) Calculate the photon flux at (per unit area per unit time) the centre of the screen and the photocurrent in the detector.
(b) If the concave lens of focal length is inserted in the aperture as shown, find the new values of photon flux and photocurrent. Assume a uniform average transmission of from the lens.
(c) If the work function of the photoemissive surface is , calculate the values of the stopping potential in the two cases (without and with the lens in the aperture).
