The electric force between two charged objects is 5.2 x 10-4 N when the objects are 3.11 x 10-1 m apart. What is the electric force between the same objects if the distance is changed to 4.04 x 10-1 m?
If possible, I would like explanations on how to arrive at these answers rather than just answering them outright as I'm trying to better understand and check the work I've already done to see if I'm correct.
As part of a laser light show, a technician is adjusting a diffraction grating. A green laser with a wavelength of 532 nm. it shines on a diffraction grating with 2700 lines/cm. The screen is 35.0 m from the diffraction grating and n = 1.
a. What is the distance between the slits of the diffraction grating?
b. How far from the central maximum, is the bright fringe?

1.what is the relationship between number of windings in the solenoid and the deflection of the galvanometer needle?
A long, straight, current-carrying wire runs from north to south.
a. A compass needle placed above the wire points with its north pole toward the east. In
what direction is the current flowing?
b. If a compass is put underneath the wire, in which direction will the needle point?
Consider three point charges at the corners of a triangle, as shown in the figure, where q1 = 8.00 x10^-9C, q2 = −4.00 × 10^−9 C, and q3 = 6.00 × 10^−9 C. Find the magnitude and direction of the resultant force on q3
