A point charge q(1)= 85.9 micro C is held fixed at the origin. A second point charge, with mass m = 6.00×10?2kg and charge q(2)= -2.36 micro C , is placed at the location (0.323 m, 0). Will rate if right, I really appreciate it. A) Find the electric potential energy of this system of charges. B)If the second charge is released from rest, what is its speed when it reaches the point (0.121 , 0)?
An electron (charge -e) is projected horizontally into the space between two oppositely charged parallel plates. The electric field between the plates is 462N/C upward.
What is the true gravitational acceleration and the centrifugal acceleration and how much work does the girl do to set herself and the merry-go-round into motion?
(a) Three point charges, A = 2.2 µC, B = 7.5 µC, and C = -3.9 µC, are located at the corners of an equilateral triangle. Find the magnitude and direction of the electric field at the position of the 2.2 µC charge.
Classical Mechanics: Projectile Motion, A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.80 m/s at an angle of 21.0° below the horizontal. It strikes the ground 3.00 s later.
define the potential difference between the plates.With what force must the player push the puck so that his force just equals the frictional force.
A 35.0-g bullet moving at 475 m/s strikes a 3.2-kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 225 m/s. How fast is the bag moving while the bullet exits.
It collides with a 10,000 kg railway car resting at the bottom of the track with its brakes off. The two cars couple together and roll up the track to a height of h. find out h.
What is the acceleration of the truck. If it starts 4.50 m from the lower edge of the roof, how fast would the toolbox be moving just as it reaches the edge of the roof if the kinetic friction force on it is 18.0 N.
Find the acceleration of the aircraft and express it in multiples of g, free fall acceleration.
Bob has just finished climbing a sheer cliff above a beach, and wants to figure out how high he climbed. All he has to use, however, is a baseball, a stopwatch, and a friend on the ground below with a long measuring tape. Bob is a pitcher, and kno..
A tuning fork vibrating at 666 Hz falls from rest and accelerates at 9.8 m/s 2. How far below point of release is the tuning fork when waves of frequency 626.4 Hz reach the release point? The speed of sound in air is 339 m/s.
calculate the average acceleration in m/s^2 (meter per second square), using a coordinate system with the X axis in the direction of the car's original motion and the Y axis toward the side of the road to which the car skids.
