question 1
A test load of 5 μC is acted on by an electric force of intensity 20 N, horizontal and from left to right, when placed at a point P in space. Determine the characteristics (intensity, direction and direction) of the electric field vector at this point.
question 2
An electric field vector at a point P has an intensity of 2 × 106 N/C, vertical direction and bottom-up direction. When a test charge, q= -1 μC, is placed at this point, an electrical force acts on it. The intensity, direction and direction of the electrical force acting on the test load are, respectively:
(a) 2 N, vertical, from bottom to top;
(b) 2 N, vertical, from top to bottom;
(c) 1 N, vertical, from bottom to top;
(d) 2×101, vertical, top to bottom;
(e) 2 × 1012, vertical, from the bottom to the top.
Among the most recurrent themes in the Languages, Codes and their Technologies test, figures of speech stand out, considering mainly the interpretative character of the Enem questions. With that in mind, we created an exercise class to see how this subject has already fallen on the exam. Don't miss watching!
