The magnetic flux through each of give faces of a neutral playing dice is given `phi_(B)=+-NWb, where N(=1 t o 5)` is the number of spots on the face. The flux is positive (out -ward) for `N` even and negative (inward) for `N` odd What is the flux thogh sixth face of the die ?

A

`3Wb`

B

`4Wb`

C

`-3Wb`

D

`-4 Wb`

Text Solution

Verified by Experts

The correct Answer is:
A
`phi_("net") = 0`
`phi_(1) + phi_(2) + phi_(3) + phi_(4) + phi_(5) + phi_(6) =0`
`-1 + 2 -3 + 4 -5 + phi_(6) = 0` .
