Column – I

Column – II

i. $I subscript 1$ is equal to
a. $21 over 32 M R squared$

ii. $I subscript 2$ is equal to
b. $I subscript 1 divided by 2$

iii. $I subscript 3 plus I subscript 4$ is equal to
c. $15 over 32 M R h 2$

iv. $I subscript 2 minus I subscript 3$ is equal to
d. none of these

$i \to c; i i \to b; i i i \to a; i v \to a$
$i \to c; i i \to a; i i i \to b; i v \to a$
$i \to c; i i \to a; i i i \to a; i v \to b$
$i \to a, i i \to d; i i i \to b; i v \to c$

The correct answer is: $i rightwards arrow c semicolon i i rightwards arrow a semicolon i i i rightwards arrow a semicolon i v rightwards arrow b$
