A 180 V Battery Is Connected Across Two Parallel Metal Plates Of Area 28 5 Cm And Separation 8 20 Mm A Beam Of Alpha P 1 (50.88 KiB) Viewed 12 times

A 180 V battery is connected across two parallel metal plates of area 28.5 cm² and separation 8.20 mm. A beam of alpha particles (charge +2e, mass 6.64 x 10-27 kg) is accelerated from rest through a potential difference of 1.75 kV and enters the region between the plates perpendicular to the electric field, as shown in (Figure 1). Figure 물 < 1 of 1 Part A What magnitude of magnetic field is needed so that the alpha particles emerge undeflected from between the plates?
