What would be the magnitude of the electric field 0.75 m from a 0.63 C master charge and what would be the force on a 0.50 C tes

bagirrra123 [75]

The magnitude of the electric field on the master charge is 1.008 x 10¹⁰ N/C, and the force on the test charge is 5.04 x 10⁹ N.

<h3>Electric field on the master charge</h3>

E = kq/r²

where;

q is magnitude of master charge
r is distance of separation
k is Coulomb's constant

E = (9 x 10⁹ x 0.63)/(0.75²)

E = 1.008 x 10¹⁰ N/C

<h3>Force on the test charge</h3>

F = Eq

where;

E is electric field
q is the test charge

F = (1.008 x 10¹⁰) x (0.5)

F = 5.04 x 10⁹ N

Thus, the magnitude of the electric field on the master charge is 1.008 x 10¹⁰ N/C, and the force on the test charge is 5.04 x 10⁹ N.

the car turned a corner going 10m/s if it took two seconds to turn what is its acceleration is this acceleration

exis [7]

The acceleration of this car is equal to 5 $m/s^2$ .

<u>Given the following data:</u>

Initial velocity = 0 m/s (assuming it's starting from rest).

Final velocity = 10 m/s.

Time = 2 seconds.

To determine the acceleration of this car:

<h3>How to calculate acceleration.</h3>

In Science, the acceleration of an object is calculated by subtracting the initial velocity from its final velocity and dividing by the time.

Mathematically, acceleration is given by this formula:

$a = \frac{V\;-\;U}{t}$

<u>Where:</u>

V is the final velocity.

U is the initial velocity.

is the time measured in seconds.

Substituting the given parameters into the formula, we have;

$a = \frac{10\;-\;0}{2}$

Acceleration, a = 5 $m/s^2$
