Pleas hel Particles 91 = -53.0 UC, 92 = -105 °C, and q3 = +88.0 °C are in a line. Particles q1 and q2 are separated by 0.50 m
and particles q2 and q3 are separated by 0.95 m. What is
the net force on particle q3?
Remember: Negative forces (-F) will point Left
Positive forces (+F) will point Right

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
