Question

1 Hour, 1 Hour, SM Question 1 1 pts A positive test charge is a distanced from the negative source charge. What happens to the magnitude of the electric field if you investigate a point at 2d instead? it gets bigger, but not by twice it gets half as big it gets smaller, but not by half it gets twice as big it stays the same Question 2 1 pts Which statements are true about electric fields? field vectors point towards positive charges field vectors point towards negative charges they only exist at locations with a test charge they are created by the presence of a charged particle Question 3 1 pts What happens to an electron placed at rest in an electric field that points to the left? it accelerates to the left it accelerates to the right it moves at constant velocity to the right it moves at constant velocity to the left

Answer 1

Dear student,

Find this solution, and RATE IT ,If you find it is helpful .your rating is very important to me.If any incorrectness ,kindly let me know I will rectify them soon.

Thanks for asking ..

at point - E = 1 + Edt if r ~ 28 then, E- so it gets smaller by 12 E 4 optim(c) istine 4 X To wards) (Away) optims (6) & (d) are true. 3 EL -F-TE = -F since election is negative charge particle so it will experience force opposite to E. le to the right- Hence, option (b) is tone, 4) if VTV along in the direction of El which is from hisher to lower potential). So optim (a) is correct. interaction Electric potential is a relative term so it depends on the reference (v=d). But it is defined at a point, not for the system (Its not a optims (B) and I are correct. And Sherry)
