🔬 Physics Lab Activity – Real Image Formation by Convex Lens

Today in the Physics lab, students performed an activity on the formation of a real image by a convex lens using an optical bench.
Students observed how the position of the object and screen affects the image formation and learned how a convex lens forms a real, inverted image on the screen.

This hands-on experiment helped students better understand the concept of image formation and focal length of a convex lens.

An infinitely long solid cylinder of radius R has a uniform volume charge density ρ. It has a spherical cavity of radius R/2 with its centre on the axis of the cylinder, as shown in the figure. Find the magnitude of the electric field at the point P, which is at a distance 2R from the axis of the cylinder.
