Using a microscope, appropriate photons can be used to visualize an electron in an atom within a distance of 0.1 Å.

A microscope using suitable photons is employed to locate an electron in an atom within a distance of 0.1 Ã…. What is the uncertainty involved in the measurement of its velocity ?

The uncertaintuy invelved in the measurement fo velocity within a distance of 0.1 Å is :

Which of the following dyes can be used to visualize nucleic acid after electrophoresis ?

The force between an alpha -particle and an electron separated by a distance of 1 Å is -

An electron in Li^(2+) ion makes a transition from higher state n_(2) to lower state n_(1)=6. The emitted photons is used to ionize an electron in H-atom from 2nd excited state. The electron on leaving the H-atom has a de Broglie wavelength lambda-12.016 "Å" .Find the value of n_(2). Note : Use (12.016)^(2)= (150xx144)/(13.6xx11),lambda_("Å")=sqrt((150)/(KE_(eV)))
