A meter bridge with two resistances R1R_1 and R2R_2 as shown in figure was balanced (null point) at 40 cm from the point P. The null point changed to 50 cm from the point P, when 16 Ω16\ \Omega resistance is connected in parallel to R2R_2. The values of resistances R1R_1 and R2R_2 are .
  1. (1)R2=16 Ω, R1=163 ΩR_2 = 16\ \Omega,\ R_1 = \dfrac{16}{3}\ \Omega
  2. (2)R2=4 Ω, R1=43 ΩR_2 = 4\ \Omega,\ R_1 = \dfrac{4}{3}\ \Omega
  3. (3)R2=8 Ω, R1=163 ΩR_2 = 8\ \Omega,\ R_1 = \dfrac{16}{3}\ \Omega
  4. (4)R2=12 Ω, R1=123 ΩR_2 = 12\ \Omega,\ R_1 = \dfrac{12}{3}\ \Omega
