What is the unit of magnetic flux?

Two elecctrical charges of 500 m(permeability)C each exert a force of 3.2 N on each other. How far apart are they? Next problem. Two electrical charges placed 100 m apart exert a Force of 6200 N on each other. What is the charge? Can anyone give the answer to these physics questions I’m stuck on?

An xray is operated at a pd of 10^5V. Calculate the minimum xray wavelength obtained from the tube.

the bar magnet is moved completely through the loop.Determine direction of the current between the two points a and b in the circuit

a wire loop of resistance 10 ohm and radius 10cm is kept in the plane of its paper in a uniform magnetic field b.the direction of b is perpendicular to the plane of the page and points out of it and it's magnitude is increasing at the rate of 0.5t/s. determine the magnitude and direction of the induced current in the loop

A double charged unknown ion is shot into a 0.845 T magnetic field between two parallel plates which are 4.00 mm apart. When a potential difference of 56.8 kV is applied across the plates, the particle passes undeflected through the fields. When the voltage is turned off, the particle has a radius of curvature of 4.15 m.

Identify the ion

A certain FM radio station broadcasts electromagnetic waves at a frequency of 9.05×10 to the seventh power HZ. These radio waves travel at the speed of 3.00×10 to the eighth power M/S. What is the wavelength of these radio waves?

a non-conducting sphere of radius 1m carrying net positive charge 18nc is enclosed by a concentric non-conducting thin spherical shell of radius 2m carrying net negative charge 20nc.determine the electric fields at the distance of 0.5m,1.5m and 2.5m ,respectively,from the centre of the sphere

A 0.015kg marble moving to the right at 0.225m/s makes an elastic head-on collision with a 0.030kg at 0.180m/s. After a collision, the smaller marble moves to the left at 0.315m/s. assume that neither marble rotates before or after the collision and both marbles are moving on a frictionless surface. What is the velocity of the 0.030kg marble after the collision?
