Hi Yash,


begin mathsize 14px style straight V subscript 1 equals straight V subscript 2 straight K straight q subscript 1 over straight q subscript 2 equals straight K straight q subscript 2 over straight q subscript 1 rightwards double arrow straight q subscript 1 over straight q subscript 2 equals straight R subscript 1 over straight R subscript 2 straight sigma subscript 1 over straight sigma subscript 2 equals fraction numerator straight q subscript 1 divided by 4 πR subscript 1 superscript 2 over denominator straight q subscript 2 divided by 4 πR subscript 2 superscript 2 end fraction equals straight q subscript 1 over straight q subscript 2 open parentheses straight R subscript 2 over straight R subscript 1 close parentheses squared straight sigma subscript 1 over straight sigma subscript 2 equals straight R subscript 2 over straight R subscript 1 end style
