Show ALL YOUR WORK! Give a detailed solution Below is a diagram of a VERY long line of negative charge (horizontal) and a positive point charge below it. (here is the diagram in pdf) A. Find the total E-field vector at Point B. (Give detailed solution & include vectors) B. Calculate the acceleration vector of an electron placed at Point B.(Give detailed solution) 8150 J. NOTE 1: Your answers should look like this: E = 4420 - 8150 NOTE 2: For this question we are not using Point A. HINT: your electric field vector should point up and to the right. Long line of charge 30.0 cm Point A 30.0 cm 2 = 25.0 nc m 60.0⁰ 15.0 cm = 4.00 nC 22.5 cm 9 = point charge Point B

Use the given information to solve part C

Consider the isosceles triangle below.a. Draw the diagram of forces on sphere A by applying the laws of electric forces if spheres B and C have negative charges and sphere A has a positive charge.b. Using vector decomposition, calculate the net electric force acting on sphere A if it has a charge of +3 x10^-6 C, if sphere B has a charge of -1.2 x10^-6 C and if the sphere C has a charge of -2.5x10^-6 C. The angle A is 78.5 degrees.

The diagram below shows a positive point charge placed near a neutral metal cube. The location marked with a × can be ignored. a. Draw the charge distribution within the metal cube and reduce it to an “effective point charge model, as shown in class.b. Is the positive point charge attracted to, repelled by, or unaffected by the metal cube? Please explain using a neat vector diagram to support your arguments.c. In a second identical experiment, the positive point charge +q is replaced by a negative point charge −q. Does a negative point charge interact differently with the metal cube as compared to the positive point charge? Briefly explain your reasoning.
