1. Two point charges are on the y axis. A 3.80-µC charge is located at y = 1.25 cm, and a -2.18-µC charge is located at y = -1.80 cm.
(a) Find the total electric potential at the origin.
V
(b) Find the total electric potential at the point whose coordinates are (1.50 cm, 0).
2. An amount of charge ±Q is placed on the plates of a parallel-plate capacitor so that the potential across the plates is ?Vinit. The capacitor is then disconnected, and the separation between its plates is increased by a factor of three. If the charge on the plates is ±34 ?C while the final capacitance is 6.0 multiply.gif 10-9 F, what was ?Vinit?
How many 104 W lightbulbs can you use in a 102 V circuit without tripping a 17 A circuit breaker? (The bulbs are connected in parallel that means that the potential difference across each lightbulb is 102 V.)
The liquid-drop model of the atomic nucleus suggests high-energy oscillations of certain nuclei can split the nucleus into two unequal fragments plus a few neutrons, Calculate the electric potential energy (in electron volts) of two spherical fragm..
A person holds a ladder horizontally at its center. Treating ladder as a uniform rod of length 3.30 m and mass 7.43 kg, find out the torque the person must exert on the ladder to give it an angular acceleration of 0.405 rad/s2.
A velodrome track is banked so that a bicycle traveling at 43.5 km/h will have no tendency to slip to either side when traveling on the path that has a radius of curvature of 59.0 m
Landing on the Moon, a spacecraft fires its retrorockets and comes to a complete stop just 19m above the lunar surface. It then drops freely to surface.How long does it take to fall in seconds? What is its impact speed in meter per seconds.
An iron bar 50 cm long is raised to a copper bar 60 cm long and of the same diameter. What is the heat flow down the rod if its cross-sectional area is 2.50 cm2
You are lowering two boxes, one on the top of the other, down the ramp by pulling on a rope parallel to the surface of the ramp.
A 10.5 kg uniform board is wedged into a corner and held by a string at a 50 degree angle. Determine the tension in the string. Hint: take torques about the corner and assume any length for the board.
A solenoid is constructed with a total of 1500 turns wound around a length of 25 cm. A constant current of 1.7 A flows through the solenoid. Calculate the magnetic force on the proton
A ball is thrown directly up from the ground with speed vsub0. At the same time, a second ball is dropped from rest from a height H, straight above the point where the first ball was thrown upward. There is no air resistance. A) Find out the time at ..
