A molecule of DNA (deoxyribonucleic acid) is 2.18 μm long. The
ends of the molecule become singly ionized: negative on one end,
positive on the other. The helical molecule acts like a spring and
compresses 1.06% upon becoming charged. Determine the effective
spring constant of the molecule.
______N/m
Two small identical conducting spheres are placed with their
centers 0.59 m apart. One is given a charge of 12 ✕ 10−9 C, the
other a charge of −17 ✕ 10−9 C.
(a) Find the electrostatic force exerted on one sphere by the
other.
magnitude_____ N
(b) The spheres are connected by a conducting wire. Find the
electrostatic force between the two after equilibrium is reached,
where both spheres have the same charge.
magnitude _____N
Rocket observations show that dust particles in Earth's upper
atmosphere are often electrically charged.
(a)
Find the distance separating two dust particles (in m) if each has
a charge of +e and the Coulomb force between them has magnitude
1.70 ✕ 10−14 N.
______ m
(b)
Calculate the mass (in kg) of one of the dust particles if this
Coulomb force would accelerate it at 3.60 ✕ 108 m/s2. (In the upper
atmosphere, effects from other nearby charges typically result in a
small net force and acceleration.)
_______kg
1)Given,
L = 2.18 x 10^-6 m ; x = 1.06% of L
We know that
F = k q1q2/r^2
q1 = q2 = e = 1.6 x 10^-19 C
F = 9 x 10^9 x (1.6 x 10^-19)^2/(2.19 x 10^-6)^2 = 4.8 x 10^-17 N
Also, F = kx => k = F/x
k = 4.8 x 10^-17/(0.0106 x 2.18 x 10^-6) = 2.08 x 10^-9 N/m
Hence, k = 2.08 x 10^-9 N/m
