السلام عليكم
سااااااااااااعدوني هذا واجب فيزيا من كلية العلوم ولم اعرف حله ويجب تسليمه للدكتور قبل الساعة الثانية عشر اليوم
ساااااااعدوني
A uniform electric field exists in the region between two oppositely charged parallel plates 1.70 apart. A proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate in a time interval 1.58×10−6 .
س1 : Find the magnitude of the electric field.
Use 1.60×10−19 for the magnitude of the charge on an electron and 1.67×10−27 for the mass of a proton.
س2::Find the speed of the proton at the moment it strikes the negatively charged plate
