7. Electrons are accelerated from rest through a potential difference as shown. The electrons then pass undeflected through mutually perpendicular electric and magnetic fields (E₁ and B₁). After passing through E₁ and B₁, the electrons pass through a different perpendicular magnetic field B2, resulting in circular motion with the given radius. e 200 V E₁ = ? B₁ = 3.00 mT Calculate the magnitudes of E₁ and B₂. r = 2.90 cm B₂ = ? [6]
