In the set up shown, the two slits S₁ and S₂ are not equidistant from the slit S

The central fringe at O is then

A group of N cells whose emf varies directly with the internal resistance as per the equation are connected as shown in the figure. The current I in the circuit is

In the circuit shown, the internal resistance of the cell is negligible. The steady state current in the 2 resistance is

Two similar accumulators each of emf E and internal resistance r are connected as shown in the following figure. Then, the potential difference between x and y is

A current of A enters one corner one corner P of an equilateral triangle having 3 wires of resistance 2each and leaves by the corner R. then the current and are

For the circuit shown in the figure the potential difference between A and B will be (in volt)

If A = and (aI₂ + bA)² = A, then-

Hence Choice 2 is correct

If A = then (A– 2I) (A – 3I) equals-

If A = and A² – KA– I₂ = 0, then value of K is-

If A = then Aⁿ equal to-

If A and B are two matrix of same order then A² – B² = (A + B) (A – B) correct statement is-

If A = then Aⁿ =

If A =, then A⁴ is equal to-

If A =, I is the unit matrix of the order two & a, b are arbitrary constant then
(aI + bA)² =

If AB = C; then A, B, C are-

The magnitude of I in ampere is
