A wave on a string is described by y ( x , t ) = 15.0 sin( πx /8 − 4 πt ), where x and y are in centimeters and t is in seconds. (a) What is the transverse speed for a point on the string at x = 6.00 cm when t = 0.250 s? (b) What is the maximum transverse speed of any point on the siring? (c) What is the magnitude of the transverse acceleration for a point on the string at x = 6.00 cm when t = 0.250 s? (d) What is the magnitude of the maximum transverse acceleration for any point on the string?

Three point-like charges are placed at the corners of a square as shown in the figure, 28.0
cm on each side. Find the minimum amount of work required by an external force to move
the charge q1 to infinity. Let q1=-2.10 μC, q2=+2.40 μС, q3=+3.60 μC.
A point charge of -4.00 nC is at the origin, and a second point charge of 6.00 nC is on the x axis at x= 0.820 mm . Find the magnitude and direction of the electric field at each of the following points on the x axis.
