Which of the following statements is NOT true about X-rays?

A proton is accelerated by a potential V and the de-Broglie wavelength associated with it is \(\lambda\). By how much potential a deuteron should be accelerated to acquire the same de-Broglie wavelength as that of a proton?

An alternating voltage \( V = V_0 \sin(\omega t + \pi/2) \) is applied across an ac circuit. As a result, a current \( I = I_0 \sin(\omega t + \pi/6) \) flows in it. The power factor of the circuit is

Two charges, \(+ 20 \, μC\) and \(+ 40 \, μC\) are placed at a separation of 4 cm. The electric potential due to the pair at the middle point of the line joining the two charges is:

The electric current in a circular coil of 3 turns produces a magnetic field \( B_1 \) at its centre. The coil is unwound and is rewound into a circular coil of 6 turns. Now on passing the same current, the magnetic field produced is \( B_2 \) at its centre. The ratio \( B_1 : B_2 \) is

The correct statement regarding a carbonyl compound with hydrogen atom on its alpha carbon is :
A. A carbonyl compound with hydrogen atom on its a-carbon rapidly equilibrates with its corresponding enol and this process is known as carbonylation.
B. A carbonyl compound with hydrogen atom on its a-carbon rapidly equilibrates with its corresponding enol and this process is known as keto enol tautomerism.
C. A carbonyl compound with hydrogen atom on its a-carbon never equilibrates with corresponding enol.
D. A carbonyl compound with hydrogen atom on its a-carbon rapidly equilibrates with its corresponding enol and this process is known as aldehyde-ketone equilibration.
