Question

A meter bridge with two resistances $$R_1$$ and $$R_2$$ as shown in figure was balanced (null point) at **$$40 \, 	ext{cm}$$** from the point **$$P$$**.
The null point changed to **$$50 \, 	ext{cm}$$** from the point **$$P$$**, when a **$$16 \, \Omega$$** resistance is connected in parallel to $$R_2$$.
The values of resistances $$R_1$$ and $$R_2$$ are

Accepted Answer

C. $$R_2 = 8 \, \Omega,\; R_1 = \frac{16}{3} \, \Omega$$

Answer

A. $$R_2 = 4 \, \Omega,\; R_1 = \frac{4}{3} \, \Omega$$

Answer

B. $$R_2 = 16 \, \Omega,\; R_1 = \frac{16}{3} \, \Omega$$

Answer

D. $$R_2 = 12 \, \Omega,\; R_1 = \frac{12}{3} \, \Omega$$
