How is the electrostatic force affected when the magnitude of a charge is doubled? the magnitude of the electrostatic force doubles the magnitude of the electrostatic force will decrease by one half. the magnitude of the electrostatic force will be quadrupled. the magnitude of the electrostatic force will be reduced to 1/4 of the original magnitude.

Achild throws a ball with an initial speed of 8.00 m/s at an angle of 40.0° above the horizontal. the ball leaves her hand 1.00 m above the ground. how long is the ball in flight before it hits the ground?
