D PART B . 1. According to Gauss’s law the flux emerging from a closed surface is given by, ∫ = ⋅ = Φ ε q A d E , where q is the net charge enclosed within the surface. Then, a) The surface S 1 encloses + q , so Φ 1 = + q / ε b) The surface S 2 encloses – 2 q , so Φ 2 = – 2 q / ε 0 c) The surface S 3 encloses q – 2 q = 0, so Φ 3 = – q / ε 2. a) b) 1 3. a) GREATER THAN 500 Hz b) EQUAL TO 500 Hz c) LESS THAN 500 Hz d) EQUAL TO 500 H 4. a) Beam A Longer wavelengths spread over larger angles. b) Beam B Faster electrons produce shorter wavelengths, and beam B has shorter wavelengths. PART C . 1. a) THE MAGNETIC FIELD IS INCREASING b) A . 5 V 020 . = = i R E R = 4.0 ×10-3 Ω = 4.0 m Ω c) dt dB A dt BA d dt d B = = Φ = ) ( E . Since A = π r ², this becomes, dt dB r 2 π = E .
