|||Four charges are oriented in a square as shown. q1 has charge + \mu C ,
q2 has charge - \mu C , q3 has charge + \mu C ,
q4 has charge - \mu C . The square has side of length a= m long.
Find the force on q3, the lower left charge.
|||Two charges are separated by a distance of r= m . One charge has a charge of q1= \mu C ,
and the other charge has q2= \mu C . What is the force of one charge on the other.
|||Three charges, q1, q2, and Q are on an axis, like this:
|||Two small conducting balls, each with mass m= kg are tied
to the ends of non-conducting strings. The strings each have a length of L= m . The balls are then each given the
same amount of charge, Q= \mu C . Due to Coulomb's law, the balls repel each other, and
the system will sit with the balls separated as shown here:
By what distance will the balls be separated (find x)?
|||Three charges are arranged in a triangle, as shown here
|||Three charges are oriented as shown here
q1=- \mu C , q2=+ \mu C , and q3=- \mu C . The distance between q1 and q3 is r2= m and the distance between q1 and q2 is r1= m . q3 is on a line that make a \theta= degree angle with the y-axis. What is the force on q1?
|||Two masses (m1 and m2) carrying equal charges, Q, are held at a distance of d= m apart.
One of the charges has a mass of m1= kg . They are released. At the instant they are
released, m1 has an acceleration of a1= m/s2 and m2 has an acceleration of a2= m/s2 .
|||Three charges are arranged as shown here.
|||Two charges, q1 and q2 have a sum of \mu C . When they are m apart, a repulsive force of N exists between them. What are q1 and q2?|
|||How many electrons are in - C of charge?|
|||Two small metal balls are r= m apart. They repel each other with a force of F= N . What is Q on each ball?|
