Two resistance wires on joining in paral...

Two resistance wires on joining in parallel the resultant resistance is ohms `(6)/(5)` ohms. One of the wire breaks, the effective resistance is 2 ohms . The resistance of the broken wire is

A

3 ohm

B

4 ohm

C

5 ohm

D

6 ohm

Text Solution

Verified by Experts

The correct Answer is:
A, D
By COLM `0 = m_(A) v_(A) + m_(B) v_(B), vec(v)_(B) = -(m_(A))/(m_(B)) vec(v)_(A)`
Both velocity are opposite in direction `:.` II, IV, V
