The Coulomb’s law is expressed mathematically as:
F = k * q1 * q2 / d^2
Where,
F = force of attraction between 2 particles = 2.0 N
<span> k = Coulomb’s
constant = 8.988 * 10^9 N m^2 / C^2</span>
q = charge of the particle
d = distance between the 2 particles = 1.35 m
Since the two coins have identical charges therefore q1 =
q2 =q
F = k* q^2 / d^2
2.0 N = (8.988 * 10^9 N m^2 / C^2) * q^2 / (1.35 m)^2
q =
2.01 * 10^-5 C
<span>Therefore each coins have charges equivalent to 2.01 *
10^-5 C.</span>
a 10 kg block reaches a point with a velocity of 15 m per second and slides down a rough track my the coefficient of the kinetic energy between the two surface ab and the block iis0.52
