السلام عليكم
محتاجة مساعدة في حل مسائل في الفيزياء ضروري خلال يومين (اليوم الأحد 19/10)
اللي عنده مقدرة يحل هالأسئلة ما يبخل ويساعدني والله يعطيه العافية
واذا ممكن خلال يومين
الأسئلة لطلاب العلوم والهندسة مستوى أول (عام) من كتاب physics for scientists and engineers (serway)fourth edition
وهاي الاسئلة
[1] (a) Find the potential at a distance of 1.00 cm from a proton. (b) What is the potential difference between two points that are 1.00 cm and 2.00 cm from a proton? © What If? Repeat parts (a) and (b) for an electron.
[2] Suppose an electron is released from rest in a uniform electric field whose magnitude is 5.90 ×103 V/m. (a) Through what potential difference will it have passed after moving 1.00 cm? (b) How fast will the electron be moving after it has traveled 1.00 cm?
[3] Over a certain region of space, the electric potential is V = 5x - 3x2y+2yz2. Find the expressions for the x, y, and z components of the electric field over this region. What is the magnitude of the field at the point P that has coordinates (1, 0, -2) m?
[4] A spherical conductor has a radius of 14.0 cm and charge of 26.0 µC. Calculate the electric field and the electric potential (a) r = 10.0 cm, (b) r = 20.0 cm, and © r = 14.0 cm from the center.
