A positive and a negative charge, each with a magnitude of 3.65 x 10-4 C, are separated by a distance of 0.67 m. Find the force
1 answer:
Answer:
The force on each charge is 2668 N and the direction of force on each charge is towards the other charge. Which means force of attraction is there between the charges.
Step-by-Step Explanation:
Let the two charges be q1 and q2
q1 = 3.65*10^(-4) C
q2 = -3.65*10^(-4) C
Distance = d = 0.67 m
We know that the magnitude of the electric force that a particle exerts on another particle is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Also, opposite charges attract each other.
Let F12 is the force on charge 1 by charge 2.
Let F21 is the force on charge 2 by charge 1.
F12 = F21 = F = kq1*q2/d^2 where k = 8.99*10^(9) N m^2 C^(-2)

Magnetic field, B = 0.0196 T
Explanation:
A current of 0.6 amps flows through a solenoid 6500 turns and 25 cm long. What is the value of the magnetic field inside it?
We have,
Current, I = 0.6 A
Number of turns in the solenoid, N = 6500
Length of solenoid, l = 25 cm = 0.25 m
The magnetic field inside the solenoid is given by :
So, the value of the magnetic field inside the solenoid is 0.0196 T.
Answer:
6.71 × 10^8 mi/hr
Explanation:
Light is usually defined as an electromagnetic wave that is comprised of a definite wavelength. It is of both types, visible and invisible. The light emitted from a source usually travels at a speed of about 3 × 10^8 meter/sec. This speed of light is commonly represented by the letter 'C'.
To write it in the metric system, it has to be converted into miles/hour.
We know that,
1 minute = 60 seconds
60 minutes = 1 hour
1 kilometer = 1000 meter
1 miles = 1.6 kilometer
Now,
=
= 1.08 × 10^12 m/ hr (meter/hour)
=
= 6.71 × 10^8 mi/hr (miles/hour)
Thus, the value for speed of light (C) in metric unit is 6.71 × 10^8 mi/hr.
