Consider a positive source charge Q, that is being held in place. A nearby negative test charge q moves from point A to point B. a) What is the direction of the electric force that the source charge exerts on the test charge? b) As the negative test charge moves from point A to point B, does the electric force cause it to speed up, slow down, or move at a constant velocity? c) As the negative test charge moves...
PLEASE HELP THX U A positive charge is placed in an electric field. It starts at rest but is free to move. What does the test charge do? It stays at rest. It moves towards the nearest negative charge only (if there is one). It moves along electric field lines in the opposite direction the arrows point It feels a force pointing tangent to the field lines and moves according to the force. Three charges, -9, +q, and -2q are...
Question 1 1 pts Consider a Gaussian surface in form of a cube shown in the picture. A charge Q is placed exactly in the center of this cube. What is the flux through each of faces of cube? 0 Q/(3 0) Not enough information to answer Question 3 1 pts When electron moves in the direction which is against direction of electric field lines we can conclude that: e. both its electric potential and electric potential energy stay constant....
Question 3 1 pts The figure shows an equilateral triangle ABC. A positive point charge +q is located at each of the three vertices A B, and C. Each side of the triangle is of length a. A point charge Q (that may be positive or negative) is placed at the mid-point between B and C a/2 Ref 18-1 Is it possible to choose the value of Q (that is non-zero) such that the force on Q is zero? Explain...
QUESTION 1 For a positive electric charge, The Electric Field of that particle points the charge. O A. toward OB. away from OC. Toward or away from , depending on the magnitude of the charge OD. neither toward or away, as the field does not depend on the sign of the charge QUESTION 2 The Electric Potential of a positive charge is O positive O negative O positive or negative depending on the magnitude of the charge the sign of...
The top left diagram below shows a 1-C positive charge placed in a uniform external electric field. The electric field in which the charge is placed is represented by field lines (drawn in red), and the resulting electric force on the charge is represented by the blue vector. Suppose the 1-C charge is removed, and is replaced, in turn, by each of the charges shown in the other three diagrams below. Assuming that the external electric field remains the same,...
