Answer:
Explanation:
Let the smaller sphere have a radius of R
Electric field on its surface( just outside the sphere) (E₀) = k Q / R²
Electric field on the surface of larger sphere
(E) = k Q / (3R)²
= k Q / 9R²
= E₀ / 9
So option e is correct.
Answer:
K = 483575 J
Explanation:
let K be the kinetic energy of the car and m be the mass of the car and v be the velocity of the car.
the kinetic energy is given by:
K = 1/2(m)(v^2)
= 1/2(1150)(29)^2
= 483575 J
Therefore, the kinetic energy of the sports car is 483575 J.
The y component of the vector is 37.7 N and the angle between the vectors is 26.2⁰.
<h3>Y-component of the vector</h3>
The y component of the vector will be determined from the resultant vector and the x component of the vector.
R² = Y² + X²
Y² = R² - X²
Where;
- Y is the y-component of the vector
- X is the x component of the vector
- R is the resultant vector
Y² = 85.2² - 76.4²
Y² = 1,422.08
Y = √1,422.08
Y = 37.7 N
<h3>Angle between the vectors</h3>
θ = arc tan (Y/X)
θ = arc tan (37.7/76.4)
θ = 26.2⁰
Thus, the y component of the vector is 37.7 N and the angle between the vectors is 26.2⁰.
