Two point charges are fixed4.0?cmapart from each other. Their charges areQ1=Q2= 6.0μC,and their masses arem1= 1.5mgandm2= 2.5mg.
Part A: If Q1 is released from rest, what will be its speed after a very long time?
Part B: If both charges are released from rest at the same time, what will be the speed of Q1 after a very long time?
A string has a linear density of 5.60 10-3 kg/m and is under a tension of 245 N. The string is 1.9 m long, is fixed at both ends, and is vibrating in the standing wave pattern shown below in the drawing. (a) Determine the speed of the traveling wave...
