two 200 pound lead balls are separated by a distance 1m. both balls have the same positive charge q. what charge will produce an

Anna [14]

Answer:

The charge is $q = 3.14 *10^{-4} \ C$

Explanation:

From the question we are told that

The mass of each ball is $m = 200 \ lb = \frac{200}{2.205} = 90.70 \ kg$

The distance of separation is $d = 1 \ m$

Generally the weight of the each ball is mathematically represented as

$W = m * g$

where g is the acceleration due to gravity with a value $g = 9.8 m/s^2$

substituting values

$W = 90.70 * 9.8$

$W = 889 \ N$

Generally the electrostatic force between this balls is mathematically represented as

$F_e = \frac{k * q_1* q_2 }{d^2}$

given that the the charges are equal we have

$q_1= q_2 = q$

So

$F_e = \frac{k * q^2 }{d^2}$

Now from the question we are told to find the charge when the weight of one ball is equal to the electrostatic force

So we have

$889 = \frac{9*10^9 * q^2}{1^2}$

=> $q = 3.14 *10^{-4} \ C$

study a 75kg person stands on a scale in an elevator what does read in n and in kg when the elevator is at rest?

Verdich [7]

To solve this problem we will use Newton's second law in order to obtain the weight of a person. The second law tells us that

F = ma

Where,

m = mass

a = Acceleration

In this particular case, the acceleration is equal to that exerted by the earth through gravitational acceleration, so if the person's weight is 75Kg and the gravity is $9.8m / s^2$ , the weight of the body will be,

$F_W =mg$

$F_W = (75kg)(9.8m/s^2 )$

$F_W = 735.75N$

When the elevator is at rest this reads 735.75N and 75Kg (The same mass of the person)
