Kinetic Energy of Ion accelerated across potential difference

[iuchem16]

An ion of 64Zn30+ with an initial kinetic energy of 9.88 keV is accelerated across a potential difference of 277 Volts. What is its kinetic energy after acceleration (in keV)?

Hi iuchem16! Welcome to PF!

An ion of 64Zn30+ with an initial kinetic energy of 9.88 keV is accelerated across a potential difference of 277 Volts. What is its kinetic energy after acceleration (in keV)?

What is the definition of potential difference, and its relation to potential energy ?

Show us what you've tried.

A potential difference of 277 volts will transfer energy of 277 ev per unit charge to the ion.

Take the charge of your ion, multiply by 277 ev, add to 9.88...
