Question

how a pen works plz your answer

Answer 1

As the pen moves across the paper, the ball turns and gravity forces the ink down the reservoir and onto the ball where it is transferred onto the paper. ... A ballpoint pen works exactly the same way. The tiny ball is held in a socket, and the back of the ball is exposed so it can pick up ink from the reservoir.
