Electron acceleration in its lowest orbit

[nmsurobert]

Homework Statement

Calculate the centripetal acceleration of an electron in the lowest Bohr orbit.

Homework Equations

no equations were given but i think i have to use a_c = v²/r
were v = 2.19 x 10⁶ m/s (speed of electron in its lowest orbit)
r = a_o = 5.29 x 10^-11m (minimum radius)

The Attempt at a Solution

so

(2.19 x 10⁶m/s)²/(5.29 x 10^-11m)

= 9.07x10²² m/s²

does this look correct?

Right if you used the right v and r and the math is right.
BTW you should also indicate direction since accel. is a vector.

Yer' welcome! That moniker was given to me at work, my 1st name being rudy. I fear there was some rationale behind it ... :-)
