A test charge is introduced into the electric field of a charge. It feels a force of 2 F where the electric feild is 4 E. What would the force on the test charge be where the electric feild is 1 E

0.5 F

Explanation:

since electric field is defined as force per charge!

so, force on test charge is directly proportional to electric field

here new electric field becomes 1/4 of old one

i.e, 4E-->1E

so force is also will become 1/4 of old one

i.e, 2F--> 1/4 × 2F =0.5 F

watch you tube or play clash royale, mainly clash royale

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
