A proton is fired from very far away directly at a fixed particle with charge q = 1.90 x 10-18 C. If the initial speed of the proton is 1.9 x 105 m/s, what is its distance of closest approach to the fixed particle? The mass of a proton is 1.67 x 10-27 kg. X The correct answer is not zero. m Submit Answer

Which of the following is a true statement about the electric force and the force of gravity? O The gravitational constant is larger than the electrical constante O The electric force follows the inverse-square rule, and gravity does not. O The electric force can be attractive or repulsive, whereas gravity only attracts. They are equal and opposite forces Q-6.0 the right

A particle with mass m = 4.50 mg and charge Q = 75.0 μC enters a region of space where there exists an electric field between two vertically arranged parallel conducting plates, which carry opposite charges - these charges establish the field between the plates. The particle enters via a hole in the positively charged plate and after a short time leaves the region via a hole in the negatively charged plate as shown in Figure 2. The field between the plates is 3, 150 ÎN C¹. If the plates are 15.0 cm apart, and the particle enters with a speed of 5.70 x 10²m s¹, determine the speed of the particle as it exits the region between the plates. V Figure 2:

A pair of charged conducting plates produces a uniform field of 20,000 N/C, directed to the right, between the plates. The separation of the plates is 50 mm. A proton is projected from plate A, directly toward plate B, with an initial speed of vo = 1.0 × 105 m/s. What is the speed of the proton as it strikes plate B? Vo Provide the solution:___ x105 m/s + +

1. Electric force and electric potential. Inside a linear accelerator, a proton (charge + ? = 1.602 × 10−19?) travels in a straight line from one point a to another point b a total distance ? = 0.50?. Along this line, the electric field is uniform with magnitude ? = 1.5 × 107? / ? = 1.5 × 107N / C in the direction from a to b. Determinea) the force on the proton;b) the work carried out on it by the field;c) the potential difference?? − ??.
