`1 Wb//m^2` is equal to

Options

A. `10^(4)` gauss
B. `4pixx10^(-3)` gauss
C. `10^(-2)`gauss
D. `10^(-4)` gauss

Answer

A

Explanation

If a charge of 1 C moving with a velocity of `1ms^(-1)` perpendicular to a uniform magnetic field experiences a force of 1 N, then the magnitude of the field is 1 T. The SI unit of magnetic field is T.
Thus ,
`1T=1NC^(-1)m^(-1)s`
`=1Wbm^(-2)`
`=1Wb//m^(2)`
In CGS system ,
`T=1tesla =10^(4)` gauss=`1 Wbm^(-2)` .
