Answer:

q = 3.87 x 10⁵ C

Explanation:

given,

Electric field, E = 8.60 x 10¹ = 86 N/C

radius of earth, R = 6371 Km = 6.371 x 10⁶ m

Coulomb constant, K = 9 x 10⁹ N · m²/C²

Charge on the earth = ?

the electric field at the point

$E =\dfrac{kq}{r^2}$

$q =\dfrac{Er^2}{k}$

inserting all the values

$q =\dfrac{86\times (6.371\times 10^6)^2}{9\times 10^{9}}$

q = 3.87 x 10⁵ C

The electric charge on the earth is equal to 3.87 x 10⁵ C

Answer:

Deceleration, Distance And Velocity

<u>Explanation:</u>

Deceleration explains the reduction in speed of the car before it comes to stop and it is opposite to acceleration.
Distance explains the location of a person from its home and its unit is meter.
Velocity explains the relative speed of an object concerning time.
It shows both the "magnitude and direction" of the object.
Deceleration and Velocity comes under vector quantity and Distance is a scalar quantity.
Vector quantity shows the distance covered and the direction of the object
Scalar quantity explains the distance moved by the object.
