    Find the Electric field at point p

    Since q3=q4 and they are opposite to each others they cancel out But as soon as I try to find the electric field of one of the charges, I need the radius which is not given. By isolating the electric field for radius E=(kq)/r^2 I now have two unknowns

    Find the step on which the hockey puck will land

    The question goes like this. A frictionless puck is slid horizontally off the top of an infinite set of stairs with a speed of 3m/s. The steps are standard size: 20cm high and 20 cm wide. Which step will the puck strike first?Since the pluck will not get faster on the x-axis, these are my...

    Solving a Ball Thrown off a Cliff: How Long Does it Take?

    This is the question: A ball is thrown with a speed of 6m/s at an angle of 25° above the horizontal from the top of a cliff. The ball strikes the ground 15 m from the bottom of the cliff. How long does it take the ball to strike the ground? How long is the cliff?Here's a visual representation...
