A conducting circular ring is rotated with angular velocity `omega` about point `A` as shown in figure. Radius of ring is a find

a. potential difference between points `A` and `C`
b. potential difference the points `A` and `D`.

Explanation

a. Here the loop is rotating .So, we can applying `e=(Bomegal^2)/2`

Using right hand rule, we can see that
`V_Cgt V_A`
`:. V_C-V_A=(Bomegal^2)/2=(Bomega(2a)^2)/2=2Bomegaa^2`
b.

Using right hand rule, we can see that
`V_DgtV_A`
`:. V_D-V_A=(Bomegal^2)/2=(Bomega(sqrt 2a)^2)/2=Bomega^2`
