Answer:
Explanation:
a
The angle each thread is making with the vertex = 16.5 degree
weight acting downwards = 66.7 x 10⁻³ x 9.8 N .
distance between two charges = 2 x 84.8 x 10⁻² sin 33/2
= .48 m
repulsive force between the two charges
= 9 x 10⁹ x q² / .48²
F = 39 x 10⁹ q²
Now, the tension in the thread be T
T cos 16.5 = mg
T sin 16.5 = F
dividing
tan 16.5 = F / mg = 39 x 10⁹ x q² / 66.7 x 10⁻³ x 9.8
.296 x 66.7 x 10⁻³ x 9.8 = 39 x 10⁹ x q²
q² = 4.96 x 10⁻¹²
q = 2.23 x 10⁻⁶ C
= 2.23 μC
A fullerene is an allotrope of carbon in the form of a hollow sphere, ellipsoid, tube, and many other shapes. Spherical fullerenes, also referred to as Buckminsterfullerenes or buckyballs, resemble the balls used in association football. Cylindrical fullerenes are also called carbon nanotubes (buckytubes).
B. Closed because otherwise the energy would "escape"
Hello!
Use the formula F = m · a to solve:
F = Force (N)
m = mass (kg)
a = acceleration (m /s²)
75 = 6.5a
a ≈ 11.54 m/s²
