Steven has a string tied to a ball and spins it around in a circle. Assuming he keeps everything else constant as he doubles the period of the string, what happens to the acceleration? Answer in terms of a ratio (if it’s twice as much acceleration, write 2, while if it’s a third of the acceleration, write 0.33). NUMERICAL answers only

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?
