21 and s2- be ordered bases for IR2. Give the change-of-basis matrix from T to 2. Show your work.
For the circuit shown below, using Ohm's law enter in an equation for IR1, IR2, IR3 IR4, IR5, and IR6,in terms of the voltage at nodes 1, (V1),2, (V2), 3, (V3), 4, (V4), R1, R2, R3, R4, R5, Rf6 A sample answer would be (V1-V2)yR1. If you are getting a syntax error, you might not be typing in the variables correctly. Do not try to add subscripts or any formatting, this will cause a syntax error as well. R1 R1...
1. A) Identical negative charges() are located at two of the three ver- tices of a right angled triangle. The charges are located at (0, a) and (a, 0). What is the magnitude of the net electric field at the third ver- tex (0, 0)? If a third identical negative charge (-Q) was located at the third vertex (i.e. at (0,0)), what would be the net electrostatic force on it due to the other two charges?
