السلام عليكم ،
أبغى إذا ممكن مساعدة في كويز مطلوب مني تسليمه يوم الثلاثاء ، حليت بعضه بس أبغى الإجابات الصحيحة والأكيدة
1) عندنا الشكل التالي :

السؤال : from the figure , which point represent equipotential surface
a-3,2,5
b-1,4
c-1 only
d-3,2 only
e-5,2 only
f-data is not enough
اخترت c
2) the figure below shows auniform electrric field . the direction in which there is no change in the electric potential is
a-1
b-2
c-3
d-4
e-5
اخترت a
3) tow positive point chargs are separated by a distance R , if the distance between the chargs is reduced to R\2 , what happens to the total electric potential energy of the system ?
a-it remains the same
b-it increases by a factor of 4
c-it is reduced to one-half of its priginal value
d-it is reduced to one-fourth of its priginal value
e-its doubled
انا اخترت a
4-if the work required to move a +0.35 C charge from point A to point B is +125 J , what is the potential diffrence between the tow points ?
a-zero
b-44V
c-88V
d-180V
e-360V
5-tow parallel horizontal plates are spaced 0.60 cm a part in air . you introduce an oil droplet of mass 7.4 x 10^(-17) kg between the plates .
if the droplet carries five electriconic charges and if there were no air buoyncy , you could hold the droplet motionless between the plates if you kept the potential difference between them at :
a-5.4V
b-27V
c-3V
d-0.54V
e-270V
على فكرة ترى انا مو تخصصي فيزياء ، يعني مُجبرٌ أخاك لا بطل
