Two small spheres spaced apart have equal charge. How many electrons must be present on each sphere if the magnitude of the force of repulsion between them is 4.57 x 10^-21 N?
Two equal positive charges q1 = q2 = 4.0 μC are located at x = 0, y = 0.30 m, x = 0, y = -0.30 m and respectively. What are the magnitude and direction of the total electric force that q1 and q2 exert on a third charge at Q = 4.0 μC x = 0.40 m, y = 0?
Two point charges are located on the -axis of a coordinate system: q1 = 1.0 nC is at x = +2.0 cm, and q2 is at x = +4.0 cm. What is the total electric force exerted by q1 and q2 on a charge q3 = 5.0 nC at x = 0?
Lightning occurs when there is a flow of electric charge (principally electrons) between the
ground and a thundercloud. The maximum rate of charge flow in a lightning bolt is about 20,000 C/s this lasts for 100 μs or less. How much charge flows between the ground and the cloud in this time? How many electrons flow during this time?
A group of five boys and eight girls go to the fair. Admission cost nine dollars per person. Which expression does not show the total amount group will pay?
The illustration above shows the attraction of two helium atom. Which is commonly known to have no charge. was it possible for 2 non-charged molecules to have an attraction?
A construction crew is lengthening a road that originally measured 41
miles. The crew is adding one mile to the road each day.
Let
L
be the length (in miles) after D
days of construction. Write an equation relating
L
to D
.Then use this equation to find the length of the road after 37
days
