If a point charge is released from rest in auniform electric field, will it follow a field line?<\/p>\n\n\n\n
The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n Correct Answer: Yes, a point charge released from rest in a uniform electric field will follow a field line.<\/strong><\/p>\n\n\n\n When a point charge is placed in an electric field, it experiences an electric force due to the field. The direction and magnitude of this force are given by Coulomb\u2019s Law<\/strong> and Newton\u2019s Second Law<\/strong>: F\u20d7=qE\u20d7\\vec{F} = q\\vec{E}<\/p>\n\n\n\n Here, F\u20d7\\vec{F} is the electric force, qq is the charge, and E\u20d7\\vec{E} is the electric field vector. If the charge is positive<\/strong>, the force acts in the direction of the electric field<\/strong>. If the charge is negative<\/strong>, the force is in the opposite direction<\/strong>.<\/p>\n\n\n\n Now, electric field lines represent the direction of the electric force<\/strong> on a positive test charge<\/strong>. So, when a point charge is released from rest in a uniform electric field, there are no initial forces other than the electric force acting on it. The charge will begin to accelerate along the direction of the electric field<\/strong> if it’s positive, or opposite the field<\/strong> if it’s negative.<\/p>\n\n\n\n In a uniform electric field<\/strong>, the field lines are parallel, straight, and evenly spaced<\/strong>, indicating that the force experienced by the charge is constant in both magnitude and direction. This results in the charge accelerating in a straight line\u2014exactly along the field line direction. The motion follows Newton\u2019s laws<\/strong>: since the net force is in one direction, the particle moves in that direction with increasing speed (assuming no other forces like friction).<\/p>\n\n\n\n Thus, yes<\/strong>, a point charge released from rest in a uniform electric field will follow a field line<\/strong>. The trajectory of the charge directly corresponds to the electric field direction, meaning its path lies along the field lines defined in the space where the field is present.<\/p>\n","protected":false},"excerpt":{"rendered":" If a point charge is released from rest in auniform electric field, will it follow a field line?
