A velocity selector in a mass spectrometer uses a 0.150 T magnetic field. (a) What electric field strength (in volts per meter) is needed to select a speed of 4.40 ✕ 106 m/s? V/m

The electric field strength is

Explanation:

Given that,

Magnetic field = 0.150 T

Speed

We need to calculate the electric field strength

Using formula of velocity

Where, v = speed

B = magnetic field

Put the value into the formula

Hence, The electric field strength is
