If the wave length decreases them deflection—

If the wave length and energy of an electron be lambda and E then show that E = h^2//2mlambda^2

If the rate of interest decreases, then the compound interest also decreases.

In a potentiometric arrangement ,a cell is connected to the potentiometer wire of 60 cm in length to make the deflection zero in galvanometer . Now if the cell is shunted with a 6Omega resistor , a null point is found in 50 cm length of the wire . What is the internal resistance of the cell ?

When the electromagnetic wave enters into a medium from free space, (A) Velocity of the wave decreases (B) Frequency of the wave decreases (C) Wavelength of the wave decreases (D) Frequency increase and wavelength decreases

If the length of a a rectangular park be increased by 2 metres and the breadth be deceased by 2 metres , then the area of the park is decreased by 26 sq . Metres . Again , if the length be decreased by 1 metre and the breadth be increased by 2 meters, then the area of the park is increased by 33 sq. metres . Find the area of the rectangular park.

A beam is supported at its ends by supports which are 12 metres apart. Since the load is concentrated at its centre, there is a deflection of 3 cm at the centre and the deflected beam is in the shape of a parabola. How far from the centre is the deflection 1 cm?

When passing through an electric field, the greatest deflection is experienced by
