Answer:
1.52g
Explanation:
Given parameters:
Force = 125N
Mass combined = 82kg
Unknown:
Acceleration of the bicycle = ?
Solution:
From Newton second law of motion suggests that:
Force = mass x acceleration
Acceleration = =
= 1.52g

Answer:
(a). The local surface charge density at the point on the surface where the radius of curvature of the surface is greatest is 123.9 nC/m².
(b). The local surface charge density at the point on the surface where the radius of curvature of the surface is greatest is 654.9 nC/m².
Explanation:
Given that,
Electric field
Electric field
When the radius of curvature is greatest, the electric field at the surface will be smaller.
Where the radius of curvature is greatest
(a). We need to calculate the local surface charge density at the point on the surface
Using formula of charge density
Put the value into the formula
The local surface charge density at the point on the surface where the radius of curvature of the surface is greatest is 123.9 nC/m².
(b). We need to calculate the local surface charge density at the point on the surface where the radius of curvature of the surface is smallest
Using formula of charge density
Put the value into the formula
The local surface charge density at the point on the surface where the radius of curvature of the surface is greatest is 654.9 nC/m².
Hence, (a). The local surface charge density at the point on the surface where the radius of curvature of the surface is greatest is 123.9 nC/m².
(b). The local surface charge density at the point on the surface where the radius of curvature of the surface is greatest is 654.9 nC/m².
