Answer:
E = 4.83 N/ C
Explanation:
If we have a uniform charge sphere we can use the following formulas to calculate the Electric field due to the charge of the sphere:
: Formula (1) To calculate the electric field in the region outside the sphere r ≥ a
Where:
K: coulomb constant (N*m²/C²)
a: sphere radius (m)
Q: Total sphere charge (C)
r : Distance from the center of the sphere to the region where the electric field is calculated (m)
Equivalences
1nC=10⁻⁹C
1cm= 10⁻²m
Data
k= 9*10⁹ N*m²/C²
Q=4nC=4 *10⁻⁹C
D = 26 cm = 26*10⁻²m = 0.26m
a = D/2 = 0.13m
r= R+a = 2.6 m+ 0.13m = 2.73m
Problem development
Magnitude of the electric field at r = 2.73m from the center of the sphere
r>a , We apply the Formula (1) :
E= 4.83 N/ C
Weight (W), the normal force( N), and the tension force( T )in the string will all be forces operating on the box.
<h3>What is tension force?</h3>The tension force is described as the force transferred through a rope, string, or wire as opposing forces pull it.
The tension force is applied along the whole length of the wire, pulling energy equally on both ends.
A horizontally pulling rope is dragging a box across the floor at a consistent speed. Friction is significant.
Hence, the force acting on the box will be weight W, Normal force N, and the tension force T, in the string.
