At time `t_(1)`, an electron is sent along the positive direction of x-axis through both an electric field and a magnetic field, with electric field directed parallel to the y-axis Graph gives the y-component of the net force on the electron due to the two fields, as a function of the electron's speed V at time `t_(1)`. Assuming `B_(x) = 0`, find magnitude of electric field in N/C and find z component of magnetic field also (Use `e = 1.6 xx 10^(-19) C`)

Answer

`1250`

Explanation

When `V=50m//s , qVB=qE rArr B=E/50`
When `V=100m//s , qVB-qE =2xx10^(-19)`
`E=1.25 N//C`
