You are given three lenses `L_1,L_2 and L_3` each of focal length 10 cm. An object is kept at 15 cm in front of `L_1` as shown. The final real image is formed at the focus `I` of `L_3` . Find the separation between `L_1, L_2 and
A potentiometer circuit is set up as shown. The potential gradient across the potentiometer wire, is `k` volt/cm and the ammeter, present in the circuit, reads `1.0` A when two way key is switched off. The balance points, when the key between the terminals (i) 1 and 2 (ii) 1 and 3, is plugged in, are found to be at lengths `l_1 cm and l_2 cm`, respectively. The magnitudes of the resistors `R and X` in ohm, are then, respectively equal
