Question

please help me with my physics assignments...its about superposition of electric fields...i have here four problem solving.....

Answer 1

whats the qsns

Answer 2

here's the first qsns...An electron (charge e= -1.6x10 C and mass of 9.1x10 kg ) is injected into a region of uniform electric field of magnitude E=1.0x10 N/C. what is the initial acceleration of the electron?

Answer 3

F=qe then a=F/m

Answer 4

im confused what is the q there

Answer 5

in the problem

Answer 6

q=E

Answer 7

ah ok..thank you!!

Answer 8

the second problem is...two charges,one of it is +1.5C and the other of +3.0C are 2.0cm apart.Where is the electric field along the line joining them equal to zero?

Answer 9

plz reply

Answer 10

equate the forces on an arbitary charge at distance 'x' from any of thw given charge

Answer 11

how?

Answer 12

F=kQq/r^2

Answer 13

after getting the F, do i still need to find the E?

Answer 14

thank you!!!!
