Shown below is a 10.0 kg block being pushed by a horizontal force F of magnitude 207.0 N. The coefficient of kinetic friction between the two surfaces is 0.60. Find the acceleration of the block. (Enter the magnitude in m/s2.)

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
