A 10 m wide spaceraft moves through the ...

A 10 m wide spaceraft moves through the interstellar space at a speed `3X10^7 ms^(-1)`. A magnetic field `B= 3 X 10^(-10) T` exists in the space in a direction perpendicular to the plane of motion. Treating the spacecraft as a conductor, calculate the emf induced across its width.

Text Solution

Verified by Experts

Here `1= 10m, v=3xx10^7m//s`
`B=3xx10^(-10)T.`
`Motional emf=Bvl`
`=3xx10^(-10)xx3xx10^7xx10`
`=9xx10^-2=0.09V.`
