In atom, there are proton and neutron inside the nucleus and electron which was moving in orbit outside of the nucleus. The electron is a negatively charged, a proton is positively charged and neutron is neutral. Since there are only proton and neutron in the nucleus it's become positively charged.
The mass of the skydiver is 122.2 kg
Explanation:
We can solve the problem by using the concept of weight.
The weight of a body is the force of gravity acting on the body; near the Earth's surface, its magnitude is given by

where
m is the mass of the body
is the acceleration of gravity
In this problem, we know the weight of the skydiver:
W = 1198 N
So we can re-arrange the equation to find its mass:
