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 directed parallel to the y-axis Graph gives the y-component `E_(max)` of the net force on the electron due to the two fields, as a function of th eelectron's speed V at time `t_(1)`. Assuming `B_(x) = 0`, find magnitude of electric field in mN//C and find z component of magnetic field also (Use `e = 1.6 xx 10^(-19) C`)

Answer

`E = 1.25 N//C, B_(z)=2.5 xx 10^(-2)T`

Explanation

When `V = 50 m//s rArr qVB_(2) = qE rArr B_(2) = (E)/(50)`
When `V = 100 m//s rArr qVB_(2) = - qE = 2 xx 10^(-19)`
`E = 1.25 N//C`.
