Four charges + 8Q – 3 Q + 5 Q and – 10 Q are kept inside a closed surface. What will be the outgoing flux through the surface,

According to Gauss’s Law, the total electric flux (Φ) through a closed surface is given by: Φ = Qenclosed/ε0 where Qₑ is the total charge enclosed within the surface. The total charge enclosed is: Q enclosed = (+8Q) + (-3Q) ...

If the roots of the quadratic equation x² – (a + 1)x + a = 0 are equal, then the value of a is:

The roots of a quadratic equation represent the x-values where the parabola intersects with the x-axis. A quadratic can have two real roots when it crosses the x-axis at two points or one real root when it touches the x-axis ...

The sum and product of the roots of the equation 2x² – 7x + 3 = 0 are:

Let me explain how to find these values without equations. When we have a quadratic expression with two roots the sum appears as the negative of the coefficient of x term divided by the coefficient of x² term. The product ...
