Transcribed Image Text:Q8. Assume the electric potential at the negatively charged plate is zero. Clearly show all
work!
a) A charged particle A with charge + 0.020 C and mass
3.0x10-8 kg is at rest as shown next to the positive plate
which has electric potential of 120 V. What is its kinetic
energy when it reaches the negatively charged plate? What
is its speed?
b) Another charged particle B with charge + 0.060 C and mass 3.0x10-8 kg is at rest as
shown. What is its kinetic energy when it reaches the negatively charged plate? What is
its speed?
c) A third charged particle C (not shown) with charge 0.070 C and mass 3.0x10-8 kg is at
rest in the middle of the two parallel plates. How much work is needed to move it to the
positively charged plate? Is the work positive or negative?
