Answer:
The center of mass for the object is from the origin
Explanation:
From the question we are told that
The mass of the first object is
The position of first object with respect to origin
The mass of the second object is
The position of second object with respect to origin
The mass of the third object is
The position of third object with respect to origin
The mass of the fourth object is
The position of fourth object with respect to origin
Generally the center of mass of the object along the x-axis is zero because all the mass lie on the y axis
Generally the location of the center mass of the object is mathematically represented as
=>

Answer:
The maximum potential difference is 186.02 x 10¹⁵ V
Explanation:
formula for calculating maximum potential difference
where;
Ke is coulomb's constant = 8.99 x 10⁹ Nm²/c²
k is the dielectric constant = 2.3
b is the outer radius of the conductor = 3 mm
a is the inner radius of the conductor = 0.8 mm
λ is the linear charge density = 18 x 10⁶ V/m
Substitute in these values in the above equation;
Therefore, the maximum potential difference this cable can withstand is 186.02 x 10¹⁵ V
