Answer:
A. 2.43 kg x 1000 g/1 kg
Explanation:
We know that the equivalence between grams and kilograms is
So, if we want to convert a mass m from kg to g, we just need to multiply the value by the factor .
In this problem, the mass is
m = 2.43 kg
Therefore, multiplying by the factor above, we get
Answer:
E = 5.65 x 10¹⁰ N/C
Explanation:
First we need to find the total charge on the sphere. So, we use the following formula for that purpose:
where,
q = total charge on sphere
V = Volume of Sphere =
σ = volume charge density = 1.5 C/m³
Therefore,
Now, we use the following formula to find the electric field due to this charged sphere:
where.
E = Electric Field Magnitude = ?
k = Coulomb's Constant = 9 x 10⁹ N.m²/C²
r = radius of sphere = 8 cm = 0.08 m
Therefore,
<u>E = 5.65 x 10¹⁰ N/C</u>
