The concept of projectile in electrostatics is a topic of interest in the world of physics. In this article, we will explore the concept of a charged particle being launched into an electric field, and how it behaves as a projectile. We will also give possible solutions to some common questions related to this topic.
Introduction and Background
Projectile motion is the path taken by an object that is flying or being thrown through the air. When a charged particle is launched into an electric field, the electric field will exert a force on it, causing it to move in a certain direction. In this case, the particle will behave as a projectile in the electric field.
The force exerted on the charged particle by the electric field is given by Coulomb’s Law. Coulomb’s Law states that the force between two point charges is directly proportional to the product of their charges, and inversely proportional to the square of the distance between them.
F = k * (q1 * q2)/r^2
where F is the force between the charges, q1 and q2 are the charges, r is the distance between the charges, and k is the constant of proportionality.
The direction of the force will depend on the sign of the charges. If the charges are of the same sign, the force will be repulsive and will cause the charged particle to move away from the other charge. If the charges are of opposite signs, the force will be attractive and will cause the charged particle to move towards the other charge.
Solution to Question 3
Let’s now take a look at the problem in Question 3. The question states that a charged particle is launched into an existing electric field, and we need to find the range of the particle. The key states that the correct option is (a).
We can approach this question by using the equations of motion for projectile motion. These equations are:
x = v0 * t * cos(theta)
y = v0 * t * sin(theta) – (1/2) * g * t^2
where x and y are the horizontal and vertical displacements respectiively, v0 is the initial velocity, theta is the angle of launch, t is the time taken, and g is the acceleration due to gravity.
We can assume that the particle is launched at a height of zero, and that the initial velocity is the same as the velocity of the electric field. The electric field has no effect on the horizontal displacement of the particle, so we can ignore the x component of the equations of motion.
Using the y component equation of motion, we get:
range = v0^2 * sin(2 * theta)/g
Since the range is zero, we can conclude that either the particle was launched vertically upward or the velocity of the electric field and the initial velocity of the particle were equal and opposite. In the latter case, the particle would not have gone anywhere and would have remained at the same position.
Conclusion
In conclusion, the concept of projectile in electrostatics is an interesting topic to study in the field of physics. Learning about how a charged particle behaves when launched into an electric field can help us understand the nature of electric fields and how they interact with charged particles. By applying the equations of motion for projectile motion, we can solve problems related to this topic and gain a deeper understanding of the behavior of charged particles in electric fields.
