Joint Entrance Examination/2000 Screening/Q006 Bohr model of an atom applied to an atom with some hypothetical particle


Welcome to the Highschool Help Forum!

The forum is currently in "Beta" stage of development. You can ask questions and answer/discuss them. The basic functionalities are present. What's required is a more aesthetic look to the Static pages and a more user friendly setup. This will happen over the time gradually as we start creating some content.

The site has a lot of tools, like posting mathematical calculations, images and diagrams; categorizing questions and so on. Having them here is NO GOOD unless you know how to use them. I am thoroughly against compiling a list of these features and then writing about them. As soon as you do not understand how to do something or use a certain feature, report that on "How To"s Section of the forum. Your queries will be answered there.

If you have any ideas/discussion regarding the site/comments, please go to Discussions regarding Highschool Help Forum

Lastly, thanks for joining in the site's development process! It matters!

Original Question by Dharav talk

Here's the question...

Imagine an atom made up of proton and a hypothetical particle of double the mass of the electron but ha. ving the same charge as the electron. Apply the Bohr atom model and consider all possible transitions of this hypothetical particle to the first excited level. The longest wavelength photon that will be emitted has wavelength X (given in terms of the Rydberg constant R for the hydrogen atom) equal to

  • (A) 9/5R
  • (B) 36/5R
  • (C) 18/5R
  • (D) 4/R?J
