find the total frictional force acting on the plate of length l, using the karman integral momentum equation g

If football was tossed in air without gravity or friction the ball would go into space

A. to determine if humans can explore mars safely

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
