two equally charged spheres of mass 1.0 g are placed 2.0 cm apart. when released, theiracceleration is414 m/s2. what is the magnitude of the charge on each sphere?

Ablock of mass 1.5 kg slides down an inclined plane that has an angle of 15. if the inclined plane has no friction and the block starts at a height of 3 m, how much kinetic energy does the block have when it reaches the bottom? acceleration due to gravity is g = 9.8 m/s2. a. 6.8 j b. 50.9 j c. 0 j d. 44.1 j
