NEET 2013 Physics Resistance MCQ Question
Type: MCQ-conceptual-Easy-Class 12
A 12 cm wire is given a shape of a right angled triangle ABC having sides 3 cm, 4 cm and 5 cm, as shown in the figure. The resistance between two ends (AB, BC, CA) of the respective sides are measured one by one by a multi-meter. The resistances will be in the ratio:
A
9 : 16 : 25
B
27 : 32 : 35
C
21 : 24 : 25
D
3 : 4 : 5
Correct Answer
Option D
Detailed Explanation
Resistance is proportional to the length of the wire. Since the sides are in the ratio 3:4:5, the resistances will also be in the same ratio.
