Two thin dielectric slabs of dielectric constants K2 and K2 (K1 2) are inserted between plates of a parallel plate capacitor, as shown in the figure. The variation of electric field E between the plates with distance d as measured from plate P is correctly shown by

Two cities are 150 km apart. Electric power is sent from one city to another city through copper wires. The fall of potential per km is 8 volt and the average resistance per km is 0.5 Ω The power loss in the wire is

The resistances in the two arms of the meter bridge are 5 Ω and R Ω , respectively. When the resistance R is shunted with an equal resistance, the new balance point is at 1.6 I1. The resistance R, is :

A potentiometer circuit has been set up for finding the internal resistance of a given cell. The main battery, used across the potentiometer wire, has anemf of 2.0 V and a negligible internal resistance. The potentiometer wire itself is 4 m long. When the resistance, R, connected across the given cell, has values of (i) Infinity (ii) 9.5 Ω, the ′balancing lengths′, on the potentiometer wire are found to be 3 m and 2.85 m, respectively. The value of internal resistance of the cell is
