The acceleration due to gravity changes as we move away from Earth, and the expression for gravitational potential energy must reflect this change. The total energy of a system is the sum of kinetic and gravitational potential energy, and this total energy is conserved in orbital motion.
Answer:
E = kQ / r^2 = 2.34*10^21 V/m
where k = 8.99*10^9 m/F
Q = 82 * 1.6*10^-19 C
r = 7.1*10^-15 m
Explanation:
14.2 FM = 2.34×10^21 V/m
Answer:
If a body is moving with uniform velocity, acceleration is zero. So net force acting on it will be also zero. But the body has energy due to its constant motion.
