Two thin hollow plastic spheres, about the size of a ping-pong ball with masses (m1=m2= 0.005 kg) have been rubbed with wool. Sphere 1 has a charge q1= -8 × 10-9 C and is at location < 0.24, -0.2, 0 > m. Sphere 2 has a charge q2= -8 × 10-9 C and is at location < -0.36, 0.35, 0> m. It will be useful to draw a diagram of the situation, including the relevant vectors. (i) If the two...
A balloon is rubbed with a wool glove. The two items attract one another with a force of strength 1.1 N when they are 1 cm apart. If they have equal but opposite charges, what is the magnitude of the charge? Submit Answer Tries 0/10 How many electrons were transferred?

Two thin hollow plastic spheres, about the size of a ping-pong ball with masses ( 0.004 kg) have been rubbed with wool. Sphere 1 has a charge -4 × 10-9 C and is at location < 0.47, -0.29, 0 > m. Sphere 2 has a charge -9 × 10-9 C and is at location < -0.42, 0.43, 0> m. It will be useful to draw a diagram of the situation, including the relevant vectors. (a) What is the relative position...
Two Ping-Pong balls each have a mass of 2.6 g and carry a net charge of 0.500 μC . One ball is held fixed. Part A At what height should the second ball be placed directly above the fixed ball if it is to remain at rest there? Express your answer to two significant figures and include the appropriate units.
A glass rod is rubbed with silk, giving it a total charge of +10nC. How many electrons or protons were added or removed? How much does the rod's mass change, in kilograms, when rubbed by the silk.
Question 2 2 pts Given: I launch the ping pong ball at 7 m/sec off of a table that is 30 inches tall. If my angle at launch is 30° Find: What angle is the ball traveling at as it hits the floor? Note that this kind of calculation can be useful for design of the target. Give the answer in degrees and measured as a positive angle from the floor. D Question 3 2 pts Given: The system in...
A charge Q is transferred from an initially uncharged plastic ball to an identical ball 32 cm away. The force of attraction is then 70 mN . a) How many electrons were transferred from one ball to the other?
