Acharge of +1 coulomb is place at the 0 cm mark of a meter stick. a charge of +4 coulombs is placed at the 100 cm mark of the same meter stick. where should a proton be placed on the meter stick so that the net force on it due to the two charges is 0? answer in units of cm

Explanation:

Let the proton is placed at the position x = x between two given charges

Now the force on this proton is zero due to two given charges

so we will have

now plug in all data

square root both sides

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
