Answer:
It becomes an Ion with either positive or negative charge
Answer:
<h3>The answer is 500 kg</h3>
Explanation:
The mass of the object can be found by using the formula
![m = \frac{2KE}{ {v}^{2} } \\](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B2KE%7D%7B%20%7Bv%7D%5E%7B2%7D%20%7D%20%20%5C%5C%20)
v is the velocity
KE is the kinetic energy
From the question we have
![m = \frac{2 \times 100000}{ {20}^{2} } = \frac{200000 }{400} = \frac{2000}{4} \\](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B2%20%5Ctimes%20100000%7D%7B%20%20%7B20%7D%5E%7B2%7D%20%20%7D%20%20%3D%20%20%5Cfrac%7B200000%20%7D%7B400%7D%20%3D%20%20%20%5Cfrac%7B2000%7D%7B4%7D%20%20%5C%5C%20)
We have the final answer as
<h3>500 kg</h3>
