    Action Encouraged

    • Clicking on the provided link encourages one to access the daily chapter-wise PDFs.

    Electrostatics

    • In an equilateral triangle, a charge Q should be placed at the centroid for the electrostatic potential energy of the system to be zero.

    Electric Potentials

    • If two charged spheres have equal surface charge density and radii R, the ratio of their electric potentials will be 1:1.

    Electric Field and Potential

    • Given the electric potential function V = 8x^3, the electric field at the point (0, -3, 1) can be calculated.
    • If 20 J of work is required to move a 4 C charge from a point with 10 V potential to another point, the potential at the final point can be calculated.

    Electric Potential at the Center of a Charged Hollow Metal Sphere

    • The electric potential at the center of a charged hollow metal sphere is zero.

    Electric Potential of Concentric Spheres

    • The electric potential at the common center of two concentric spheres with radii R and r, equal surface charge density, and kept in air can be calculated.

    Electric Field Intensity

    • The intensity of the electric field at point (-2, 1, 0) due to a point charge given by ˙V=3x^2+5 can be calculated.

    Work Done in Carrying an Electric Charge

    • The work done in carrying an electric charge Q₁ once round a circle of radius R with a charge Q at the center of the circle can be calculated.

    Kinetic Energy of an Electron

    • The kinetic energy of an electron accelerated in a potential difference of 100V can be calculated.

    Potential Difference between Conducting Spheres

    • The potential difference between a small conducting sphere inside a bigger hollow conducting sphere charged with Q and q can be calculated.
