How does the electrical force relate to the charge of an object?

Answer:

It is directly proportional to the charge

Explanation:

The magnitude of the electrical force on a charge is given by:

F=qE

where

q is the magnitude of the charge

E is the magnitude of the electric field acting on the charge

From the formula, we see that F (the force) is directly proportional to q /the magnitude of the charge), so the correct answer is

It is directly proportional to the charge

We can also add something about the direction of the force:

- when the charge is positive, the force has positive sign, which means that its direction is the same as the direction of the electric field (repulsive force)

- when the charge is negative, the force has negative sign, which means that its direction is opposite to the direction of the electric field (attractive force)

how long would it take for a resultant upward force of 100N to increase the speed of 50kg object from 100m/s to 150m/s​
ValentinkaMS [17]

Answer:

25 sec

Explanation:

F = ma

100 = 50 a

a = 2 m/s^2

vf = vo + at

150 = 100 +  2 t

50 = 2 t

t = 25 sec

An Airbus A380 airliner can takeoff when its speed reaches 80 m/s. Suppose its engines together can produce an acceleration of 3
Tomtit [17]

Answer:

(a). The time is 26.67 sec.

(b). The distance traveled during this period is 1066.9 m.

Explanation:

Given that,

Speed = 80 m/s

Acceleration = 3 m/s

Initial velocity = 0

(a). We need to calculate the time

Using equation of motion

v = u+at

t = \dfrac{v-u}{a}

Put the value into the formula

t = \dfrac{80-0}{3}

t =26.67\ sec

The time is 26.67 sec.

(b). We need to calculate the distance traveled during this period

Using equation of motion

s = ut+\dfrac{1}{2}at^2

s = 0+\dfrac{1}{2}\times3\times(26.67)^2

s =1066.9\ m

The distance traveled during this period is 1066.9 m.

Hence, This is the required solution.
