We know that the direction of electric field is from positive to negative charge. As the proton has the positive charge so if it moves in the direction opposite of electric field, it means that the positive charge will move towards the positive region. As the positive charge is attracted towards negative and repelled by the positive charge. So the work done will be negative in bringing the positive charge towards the positive region of the field and potential energy increases in the direction opposite to electric field. As the potential energy decreases in the direction of electric field.
Answer: Charles' Law: The Temperature-Volume Law. This law states that the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature. As the volume goes up, the temperature also goes up, and vice-versa.
Explanation:A force acting on a particle of mass 200 g displaces it through 400 cm in 2 seconds. Find the magnitude of the force if the initial velocity of the particle is zero ... A steel ball of mass 50 g is thrown vertically downwards with a velocity of 15 ... The weight of the body is 19.6N, the mass of the body is (g=9.8ms−2).
