Answer:
Length of displacement vector = 7.51 m
Explanation:
Consider east as positive X axis and North as positive Y axis.
Eric headed 6 meters east, Displacement = 6 i
Then he headed X meters north, Displacement = X j
Total displacement = 6 i + X j
Angle it makes with horizontal axis, θ = tan⁻¹(X/6) = 37°
X/6 = tan 37
X = 4.52 m
Total displacement = 6 i + 4.52 j
Magnitude =
Length of displacement vector = 7.51 m

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
