Answer #1

An electron (mass m1 = 9.11 x 10-31 kg) and a proton (mass m2 =
1.67 x10-27 kg) attract each other via an electrical force. Suppose
that an electron and a proton are released from rest with an
initial separation d = 3.50 x 10-6 m. When their separation has
decreased to 1.40 x 10-6 m, what is the ratio of (a) the electron's
linear momentum magnitude to the proton's linear momentum
magnitude, (b) the electron's speed to the proton's...

A. The mass of an electron is 9.11×10−31 kg. If the de Broglie
wavelength for an electron in a hydrogen atom is 3.31×10−10 m, how
fast is the electron moving relative to the speed of light? The
speed of light is 3.00×108 m/s. Calculate your answer as a
percentage.The solution was .732% B. The mass of a golf ball is
45.9 g . If it leaves the tee with a speed of 70.0 m/s , what is
its corresponding wavelength?...

Chapter 7, Problem 1. A proton (mass m = 1.67 × 10-27 kg) is
being accelerated along a straight line at 5.40 × 1013 m/s2 in a
machine. If the proton has an initial speed of 6.20 × 105 m/s and
travels 2.40 cm, what then is (a) its speed and (b) the increase in
its kinetic energy?

(1) A proton (mass m = 1.67 ✕ 10-27 kg) is
being accelerated along a straight line at 3.4 ✕ 1015
m/s2 in a machine. The proton has an initial speed of
2.4 ✕ 107 m/s and travels 4.1 cm.
(a) What is its speed? (Give your answer to at least four
significant figures.)
(b) What is the increase in its kinetic energy?

The mass of a proton, mp, is estimated to be 1.67×10^−27 kg, and
the mass of an electron, me, is estimated to be 9.109 ×10^−31 kg.
How many protons would it take to make a mass of 1g? 1kg? 1kg? How
many electrons would it take to make a mass of 1g? 1kg?

A beam of electrons (m = 9.11 × 10-31 kg/electron) has an
average speed of 1.0 × 108 m/s. What is the wavelength of electrons

A proton of mass mp = 1.67 × 10-27 kg and charge qp = 1.602 ×
10-27 C is in an electric field of E = 10 N/C that points upwards.
Draw a free body diagram for the proton, and calculate the
electrical-to-gravitational force ratio: FE/FG. Finally, remark on
whether the gravitational force is likely to be significant for an
electron in an 10 N/C electric field.
