An equilateral triangle with side lengths of 0.50 m has a 5.0 nc charge placed at each corner. what is the magnitude of the electric field at the midpoint of one of the three sides? (a) 240 n/c (b) 180 n/c (c) 720 n/c (d) 480 n/c (e) 120 n/c

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
