Check Your Understanding What is if v=0.650c?
A positively charged oil droplet remains in the electric field between twohorizontal plates, separated by a distance 1 cm. If the charge on the drop is3.2 x 10^-19 C and the mass of the droplet is 10^-14 kg what is the potentialdifference between the plates? Now if the polarity of the plates is reversedwhat is the instantaneous acceleration of the droplet?
An electron (rest mass 9.11x10-31kg, charge is -1.60-19C) is moving opposite to an electric field of magnitude E=5x105N/C. All other forces are negligible in comparison to the electrtic field force.

Two protons (each with a mass of 1.7 x 10 -27 kg and charge 1.6 x 10 -19 C)interact with each other electrically from a distance of 2 meters. If releasedfrom rest at this distance, what will their acceleration be immediately afterbeing released?
If two protons are traveling parallel to each other in the same direction andat the same speed, Is the net force between them(a) attractive or (b) repulsive?ANSWER: ______________________________________(EXPLAIN YOUR OPTION IN ONE SENTENCE ONLY)
Which of the particles as shwon has the greatest mass, assuming all have identical charges and velocities?
Two large parallel plates have been oppositelycharged. There is a uniform electric field E~present between the plates, as shown in the fig-ure. A proton, with mass mp, is released fromthe positive plate at the same moment as an elec-tron, with mass me, is released from the negativeplate. Ignore the force that the two charges exerton each other. What fraction of the way to thenegative plate has the proton moved by the timethe electron passes it?
Suppose a speck of dust has a charge on it of a microcoulomb, that is 10-6 C. If it has a mass of 0.002 gm, that is 2x10-6 kg or 2 milligrams, what acceleration does it feel in a field of 1000 V/m?
Suppose a droplet of unknown mass remains suspended against gravity when electric field is -2.70×10^5N/C. What is the minimum mass of the droplet.
If an electron travels 0.200 m from an electron gun to a TV screen in 37.5 ns, what voltage was used to accelerate it? (Note that the voltage you obtain here is lower than actually used in TVs to avoid the necessity of relativistic corrections.)
Nobel laureate Richard Feynman (19181088) once said that if two persons stood at arms length from each other and each person had 1% more electrons than protons, the force of repulsion between them would be enough to lift a weight equal to that of the entire Earth. Carry out an order-of-magnitude calculation to substantiate this assertion.
