The time period t of a simple pendulum is given by the relation

t=2pi sq rt l/g

, where l is the length of the pendulum and g is the gravitational field at the place. from the above relation, we can say that:

t ∝ g

t ∝ l

t2 ∝ g

t2 ∝ l

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?
