Two point charges are fixed on the y axis: a negative point charge q1 = -34 μC at y1 = +0.18 m and a positive point charge q2 ar

t y2 = +0.33 m. A third point charge q = +8.1 μC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two charges has a magnitude of 31 N and points in the +y direction. Determine the magnitude of q2.

Answer:

Explanation:

Field by negative charge will be more as net force due to both the charges is in positive y - direction.

field by negative charge at origin

= 9 x 10⁹ x 34 x 10⁻⁶ / .18²

= 9.45 x 10⁶ N /C

field by positive  charge at origin

= 9 x 10⁹ x Q / .33²

= 82644.63 x 10⁶ Q N /C

Net field

= 9.45 x 10⁶ - 82644.63 x 10⁶ Q

force on charge 8.1 x 10⁻⁶ C

( 9.45 x 10⁶ - 82644.63 x 10⁶ Q ) X 8.1 x 10⁻⁶  = 31

76.545 - 669421.5 Q = 31

669421.5 Q = 45.545

Q = 45.545  / 669421.5

= 68 X 10⁻⁶ C

= 68 μC

Suppose the green car was traveling at 0 miles the white car was traveling at 70 miles at the red car was trailing at 22 miles w
Elan Coil [88]

Answer:

The white car will cover the most distance every second.

Explanation:

The formula for the uniform speed of an object is given as follows:

s = vt

where,

s = distance covered by the object

v = speed of the object

t = time required

Now, if we assume time to be  constant at 1 s. Then the distance covered by each car will be directly proportional to the speed of the car. Hence, the car with the greatest speed will travel the greatest distance in 1 second.

We, have:

Speed of white car > Speed of red car > Speed of green car

<u>Therefore, the white car will cover the most distance every second.</u>

Ivanshal [37]
Well, an equilibrium means that no force are changing an object's inertia (current state of motion).
