Asmall sphere with a charge of − 0.60 μc is placed in a uniform electric field of magnitude 1.2 × 106 n/c pointing to the west. what is the magnitude and direction of the force on the sphere due to the electric field

Force on a charge placed in electric field is given by

here

magnitude of force is given by

Direction of force is opposite to electric field direction as it is a negative charge

so direction is towards EAST

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

compass can be used day and night, cloudy or sunny
