A proton (+q =+1.602 x 10^-19) moves along a straight line from point a to point b with a separation distance d = 0.50m. Considering the electric field along this line uniform magnitude of 1.50 x 10^7V/m and directed from point a to point b.
Determine:
a.) the force on the proton
b.) the work done on it by the field (in Joules & eV units)
c.) the potential difference (V ab)
Create a project to model student with firstname, lastname, age, gender and student number. Create two construtors, one to be used as default and another to include all attributes. Add a class attribute to keep count of all registered students. Use the class attribute to generate student numbers with the following format 22201XYZ, where XYZ is the current count provided by the class attribute. Implement the respective getters and setters for each attribute. 2. In plane geometry, the x- and y axis of a 2D Cartesian system divide it into four infinite regions called quadrants. Your task is to model each point with an x-value and y-value. Apart from the constructors, getters and setters, implement a getQuadrant method to determine the region in which a given point falls.
A positive charge, q = +20 nC, is on the y-axis at y = +4.00 cm.
(a) Determine the magnitude and direction of the electric field at the origin.
(b) What will be the magnitude and direction of the electric field at the origin if the charge is -20 nC?
Friend and Enemy
A group of F friends went to a haunted house.Each member was given a shirt with a number on it ranging from 1 to F. As they entered the haunted house, one of them was kidnapped and an enemy joined them.But unfortunately, the enemy didn't wear the shirt with the same number as the kidnapped one, instead wore the same as some other person.Find the numbers on the shirts of the enemy and the kidnapped person.
Input
The input is a single line containing space-separated positive integers from 1 to F.
Output
The output should be a single line containing the shirt numbers of the enemy and kidnapped person separated by a space.
Explanation
The given array is 3 1 5 2 1.
In the range from 1 to 5, the number 1 has occured twice and 4 is the missing number. So, 1 belongs to the enemy's shirt, and 4 belongs to kidnapped.Hence, the output should be 1 4.
Sample Input1
3 1 5 2 1
Sample Output1
1 4
Sample Input2
1 2 2 4
Sample Output2
2 3
Two charges are on the x-axis. Charge q1 = +25 nC is at x = 4.00cm while charge q2 = -75nC is at x = 7.00 cm,
Find the magnitude and direction of:
a.) the electric force that q1 exerts on q2; and
b.) the electric force the q2 exerts on q1.
