With what radius do the proton and electron move in circles inside the B-field region?
Consider the following circuit: 2 1 2 Suppose for this circuit, V-12V, R1-4 kQ, R2-12 kΩ and C-10mF. The capacitor is uncharged. (a) What is 11 when the switch is first closed? (3 Marks) (b) What is 12 when the switch is first closed? (1 Mark) (c) What is the value of I when the switch is first closed? (2 Mark) (d) What is the RC time constant for this circuit? (2 Marks) (e) Derive a general expression for /2 at time of t? (3 Marks) (f) What is the current through resistor 2 at time t 2 minutes? (2 Marks) An electron is traveling in a straight line heading East through a region with a uniform electric field of 3 N/C directed upwards. In the region there is also a uniform magnetic field with a strength of 2 T (a) What must be the direction of the B-field? Explain your reasoning. (3 Marks) (b) What is the speed of the electron? (2 Marks) (c) If a proton were sent in to this region (with the same speed) what would be different about its motion compared to the electron’s motion? Explain. (2 Marks) (d) The electric field is suddenly turned off. With what radius do the proton and electron move in circles inside the B-field region? (4 Marks)
