An electron is initially moving to the right when it enters a uniform electric field directed upwards, as shown in the figure. Which trajectory , or W will the electron follow in the field?
A) trajectory W
B) trajectory x
C) trajectory Y
D) trajectory Z
The figure shows two tiny 5.0-g spheres suspended from very light 1.0-m- long threads. The spheres repel each other after each one is given the same positive charge and hang at rest when heta =4.1deg . (a) Please draw the free body diagram of both spheres. (b) What is the charge on each sphere? (k)=(1)/(4)pi epsi _(0)=(9.0 imes 10^(9)(N)*(m^(2))/(C^(2)))
