Electric Field at the Center of a Square

Physics Ninja looks at a problem of calculating the electric field at the center
of a square. Point charges are placed at the 4 corners of the square the field from each charge is considered. The total electric field is the vector sum of the 4 fields.

One doubt.... answer
q3 is negative 5 and q2 is negative 5 ., then what is the direction of force on q2 due to q3 ?

Good evening Sir
Could you please upload the video of Electric Field and Electric Field Intensity?

hello I have a suggestion that might make it more simple without having to use cos or x and y component. You could apply pythagorean theorum on one of the triangles of this square. In that way you don' t have to devide the length in 2 and wouldn't have to use a 45 degree angle or cos.

I thought we use sin to find y-components ?
