Resistance of our body is given as

voltage applied across the body is

now by ohm's law current pass through our body is given by

![i = \frac{120}{30,000}[\tex][tex]i = 4 * 10^{-3} A](https://tex.z-dn.net/?f=i%20%3D%20%5Cfrac%7B120%7D%7B30%2C000%7D%5B%5Ctex%5D%3C%2Fp%3E%3Cp%3E%5Btex%5Di%20%3D%204%20%2A%2010%5E%7B-3%7D%20A)
So current from our body will be 4 * 10^-3 A
A resistance of 990ohm is increased by 10
The plane has a centripetal acceleration <em>a</em> of
<em>a</em> = <em>v</em> ²/<em>r</em>
where <em>v</em> is the plane's tangential speed and <em>r</em> is the radius of the circle. By Newton's second law,
<em>F</em> = <em>mv</em> ²/<em>r</em>
Solve for the mass <em>m</em> :
<em>m</em> = <em>Fr</em>/<em>v</em> ² = (3000 N) (18.3 m) / (55.0 m/s)² ≈ 18.1 kg
