Friction creates heat between two objects rubbing together, and slows the moving object down.
Answer:
2.94 × 10²⁰ N/C
Explanation:
Given that:
The nucleus of "Lead-208 has 82 protons,
with a radius (r) 6.34×10-15 m, &
each electric charge has a value of 1.60218 × 10^-19 C
∴ The formula for calculating an electrical field at the surface of the nucleus is:
Substituting our values into the equation above, we have;
E = 
E = 2.93870499×10²⁰ N/C
E ≅ 2.94 × 10²⁰ N/C
