A charge +1 is situated at the point 1,0,0 and a charge 1 is situated at the point (1,0,0). Find the electric field of these two charges at an arbitrary point (0,y,0) on the y-axis.
The sum of 6 times a number and 2/3 is equal to the difference of 7 times the number and 3/4. Find the number.
Consider a no-load mutual fund with $900 million in assets and 24 million shares at the start of the year, and $1,040 million in assets and 16.42 million shares at the end of the year. During the year investors have received income distributions of $4.50 per share, and capital gains distributions of $3.14 per share. Assume that the fund carries no debt. What is the NAV at the START of the year? What is the NAV at the END of the year? What is the rate of return on the fund?

Problem 3) (15pts) For the truss shown, remove support C and determine the vertical deflection at E by VWM and the horizontal deflection at E by CST. Put back support C and by the method of least work, determine the member force of CF and the reaction at C. For both cases, E=200 GPa and cross-sectional area for all members is 500 mm$^2$.
