The diagram shows a negative charge moving in a magnetic field. in which direction is the magnetic force acting on the charge? right, left, into the screen, or out of the screen

By right hand rule direction of force will be towards left

Explanation:

Here we know that force due to magnetic field on moving charge is given by

here as we can see the figure

v = velocity of charge coming out of the plane

B = magnetic field vertically downwards

q = negative charge

so from above equation of force we will have

so direction of force will be towards left

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
