Q. Two very large charged parallel metal plates are 10.0 apart and produce a uniform electric field of 2.80×106 between them. A proton is fired perpendicular to these plates with an initial speed of 5.20 , starting at the middle of the negative plate and going toward the positive plate. How much work has the electric field done on this proton by the time it reaches the positive plate?
Q. In a head on collision, a car stops in .10 seconds from a speed of 14 meters per second. The driver has a mass of 70 kg, and is, fortunately, tightly strapped into his seat. What force is applied to the driver by his seat belt during that fraction of a second?
Charge is distributed with constant volume density D throughout the rectangular box with length a, width b and height c.
A particular nucleus of the element plutonium contains 94 protons and 150 neutrons. What is the magnitude of the force from the nucleus on a single electron that is at a distance of 0.563 × 10-12 m from the plutonium nucleus.
A charge of -3.80 nC and a charge of -6.00 nC are separated by a distance of 60.0 cm. Find out the position at which a third charge of +7.30 nC could be placed so that the net electrostatic force on it is zero.
What is the distance between deer a and c
At what position is the third bead in equilibrium? Can it be in stable equilibrium.
lady ate a whole medium size pizza storing up 120 food Calories. This energy is used to heat up 2 liters of water from a certain initial temperature to a final temperature of 80 deg.C, what was the initial temperature of the water?
How many 95W light bulbs can you use in a 120V circuit without tripping a 17A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each light bulb is V.)
Given that 12g of carbon combines with 16g of oxygen to form carbon monixide, how various grams of carbon monoxide can be made from 48g of carbon and 48g oxygen.
An infinitely long line of charge has linear charge density 4.00 10-12 C/m. A proton (mass 1.67 10-27 kg, charge +1.60 10-19 C) is 17.0 cm from the line and moving straight toward the line at 3000m/s.
