Question

1. A proton has a kinetic energy of 10 eV when it is at point A in the figure. The proton moves in a vacuum and follows the trajectory shown in the figure. What is its kinetic energy when it passes point B

2. What will happen to bulb A when the switch is closed?

3. At the point labelled "3", in what direction will a compass needle point?

4. Which of the following represents the right pair of graphs for the voltage V(t) and I(t) for a discharging capacitor.

5. What is the equivalent capacitance of this circuit fragment?

A proton has a kinetic energy of 10 eV when it is at point A in the figure. The proton moves in a vacuum and follows the trajectory shown in the figure. What is its kinetic energy when it passes point B? 30 V 10 V 10 V Select one: O A. 20 eV O B. 30eV O C. 50 ev D. 40 ev E.O eV

Explanation / Answer

(KE + UE)i = (KE+UE)f

10eV +30eV = KEf - 10 eV

KEf = 50 eV

second prob

bulb will briten up because current will increse

third pprob

C is correct

fourth prob

A is correct

five problem

20 & 60 are in series and 10 with parallel   

in capacitor addintion they act exactly opposite of resistance addition

so net capacitance

= 8.9 micro F
