5. Let's try another one of electric field combination
questions for the practice. Source particle 1 is
located at coordinates (4,1) cm and source 2 at (-4,-4)
cm. Source 1 has charge -3 „C while source 2's
charge is 4 „C. What is the total electric field at the
target location, (5,6) cm?
[Enter your answer with the following format:
X*i+Y*j, where you substitute the numerical
values of the components along the - and ,
directions in place of the 'X' and 'Y' in the
expression. The letters i and j represent the unit
vectors along different directions. Use the
asterisks to denote multiplication. Make sure to
convert your units to standard MKS base units and
use two-decimal precision. Denote powers of ten
with engineering notation, for example 1.23 x 10
should be expressed as '1.23E-45'.]
