An electron is moving east with a speed 6.00 x 10° m/s in a uniform electric field. Magnitude of the electric field is 2.00 N/C directed to the west. What is the speed of the electron when it travels 0.50 m in the east direction? Please write your answer in km/s.

A proton has a mass of about 1.673x10-27kg.  If an electron is placed in a region of space within which a constant electric field exists with magnitude 4.156 N/C, how long would it take this proton to travel a distance of 649.72m in units of ms (milliseconds)?  Assume the proton does not collide with anything along the way.  Hint: You will need to use the kinematic relationships for linear motion that we learned back in PHY 2010.  This results of this problem show you that small charges like protons, and electrons too, move great distances in a short amount of time under very small external electric fields - if those charges are in a vacuum - otherwise, they quickly strike a nearby charge.

A constant  electric field accelerates  a proton from rest through  a distance of 1.90 m to a speed of 1.57 × 10^5  m/s. ( The mass  and charge of a proton are mp= 1.67×10^-27 kg ans qp= e= 1.60 × 10^-19 C.) a) Find the change in the protons kinetic energy ( in J).  b) Find the change in the system's electric potential  energy ( in J). c)Calculate the magnitude of the electric field ( in N/C).

A proton with speed v =3×105×105m/s orbits just outside a charged sphere of radius r =1 cm. The charge on the sphere is:

Calculate the gravitational force between these two protons. Newton’s gravitational constant is 6.7 × 10−11 N · m2 /kg2 and the mass of the proton is 1.7 × 10−27 kg. Answer in units of N.

Beams of high-speed protons can be produced in "guns" using electric fields to accelerate the protons. (a) What acceleration would a proton experience if the gun's electric field were 2.96 × 104 N/C? (b) What speed would the proton attain if the field accelerated the proton through a distance of 0.875 cm?

An electron is to be accelerated in a uniform electric field having a strength of 2.3·106  Vm. a)    What energy in keV is given to the electron if it is accelerated through 0.35 m? b)    Over what distance (in km) would it have to be accelerated to increase its energy by 58 GeV?

A proton accelerates from rest in a uniform electric field of 590 N/C. At one later moment, its speed is 1.00 Mm/s (nonrelativistic because v is much less than the speed of light). (a) Find the acceleration of the proton. 5.65e10 v m/s? (b) Over what time interval does the proton reach this speed? 1.79e-8 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. s (c) How far does it move in this time interval? 8.85e-6 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m (d) What is its kinetic energy at the end of this interval? 8.35e-22 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. J
