A charged particle moves under the influence of an electric field. Its x-position and y-position, as a function of time, are observed to be
x(t) = 4 + 3t + t2
y(t) = 6− 4t + 0.5t2
meters, where the x- and y-direction are east and north, respectively. Letˆi andˆj denote unit vectors in the eastward and northward direction.
a) At t = 2, what is the particle’s velocity? Express your answer as a vector usingˆi,ˆj notation, and also by specifying the magnitude and direction.
b) At t = 2, what is the particle’s acceleration? Again, useˆi,ˆj notation,and also specify the magnitude and direction.
c) How fast is the particle moving at the moment it is moving due east?
A proton initially moves left to right long the x axis at a speed of 9,070 m/s. It moves into an electric field, which points in the negative x direction, and travels a distance of 0.7 m before coming to rest. If the proton's mass and charge are 1.67 × 10−27 kg and 1.60 × 10−19 C respectively, what is the magnitude of the electric field?
To study the properties of various particles, you can accelerate the particles with electric fields. A positron is a particle with the same mass as an electron but the opposite charge (+e). If a positron is accelerated by a constant electric field of magnitude 301 N/C, find the following.
(a) Find the acceleration of the positron.
