A particle of charge `- 16 xx 10^(-18)` C moving with a velocity `10 ms^(-1)` along the x-axis enters a region where a magnetic field of magnitude B is along the y-axis and an electric field of magnitude `10^(4)` V/m is along negative z-axis . If the charged particle continues moving along x-axis , find magnitude of B .

Options

A. `10^(6) Wb//m^(2)`
B. `10^(6) Wb//m^(2)`
C. `10^(-3) Wb//m^(2)`
D. `10^(3) Wb//m^(2)`

Answer

D

Explanation

`v = (E)/(B) :. B = (E)/(v) = (10^(4))/(10) = 10^(3) Wb//m^(2)`
