Let the initial velocity of the car be u.
Final velocity of the car (v) = 5.43 m/s
deceleration (a) = - 2.78 m/s^2
Time taken (t) = 2.26 s
Using the first equation of motion:
v = u + at
u = v - at
u = 5.43 + 6.28
u = 11.71 m/s
Let the car's displacement be x.
Using second equation of motion:
x = 26.4646 - 7.0995
x = 19.3651 meters
Hence, the displacement of the car is 19.36 meters
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>
