Example 15.1 The Forces in a Hydrogen Atom Goal Contrast the magnitudes of an electric force and a gravitational force. Problem The electron and proton of a hydrogen atom are separated (on the average) by a distance of about 5.30 x 1011 m. Find the magnitudes of the electric force and the gravitational force that each particle exerts on the other, and the ratio of the electric force, Fe, to the gravitational force, Fo Strategy Solving this problem is just...

PRACTICE IT Use the worked example above to help you solve this problem. Tiny droplets of oil acquire a small negative charge while dropping through a vacuum (pressure = 0) in an experiment. An electric field of magnitude 5.60 x 10 N/C points straight down. 4 (a) One particular droplet is observed to remain suspended against gravity. If the mass of the droplet is 4.08 X 1032 kg, find the charge carried by...

Use the worked example above to help you solve this problem. A proton is released from rest at x = -2.90 cm in a constant electric field with magnitude 1.50 times 10^3 N/C, pointing in the positive x-direction. (a) Calculate the change in potential energy when the proton reaches x = 4.96 cm. The response you submitted has the wrong sign. J (b) An electron is now fired in the same direction from the same position. What is its change...

PRACTICE IT Use the worked example above to help you solve this problem. Charge q1 6.90 uC is at the origin, and charge 92 =-4.90 pC is on the x-axis, 0.300 m from the origin (see figure). (a) Find the magnitude and direction of the electric field at point P, which has coordinates (O, 0.400) m. 2.53e5 magnitude Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake...

In
the Bohr model of the atom, an electron can be thought of a small
sphere that rotates around the nucleus. In a hydrogen atom, an
electron (me=9.11 x 10^-31 kg) orbits a proton at a distance of 5.3
x 10^-11 m from the proton. If the proton pulls on the electron
with a force of 9.2 x 10^8 N, how many revolutions per second does
the electron make?

An electron is a subatomic particle (m = 9.11 x 10-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +9.00 x 105 m/s to a final velocity of 2.45 x 106 m/s while traveling a distance of 0.0949 m. The electron's acceleration is due to two electric forces parallel to the x axis: F^1 = 9.41 x 10-17 N, and F^2, which points in the -x direction. Find...

An electron is a subatomic particle (m = 9.11 10-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +5.46 105 m/s to a final velocity of +1.93 106 m/s while traveling a distance of 0.041 m. The electron's acceleration is due to two electric forces parallel to the x axis: vector F 1 = +8.15 10-17 N, and vector F 2, which points in the -x direction. Find...
