A converging lens of focal length 7.550cm is 20.5cm to the left of a diverging lens of focal length -6.50cm. A coin is placed 18.2cm to the right of the diverging lens.
A) find the location of the coins final image
B) Find the magnification of the coins final image.
A projectile is fired at such an angle from the horizontal that vertical component of its velocity is 49 m/s. The horizontal component of its velocity is 61 m/s.
Determine the position q1 of the image formed by the first converging lens.
The ball is in equilibrium, with the thread making an angle of 30.0o with respect to the vertical. The area of each plate is 0.01381 m2. What is the magnitude of the charge on each plate?
