- Question 12K4Two identical point charges (q = +1.00 x 10-6 C) are fixed at opposite corners of a square whose sides have a length of 0.420 m. A test charge (90 = -7.50 × 10-8 C), with a mass of 2.80 x 10-8 kg, is released from rest at one of the corners of the square. Determine the speed of the test charge when it reaches the center of the square. Number i Units .90 VB
- Item 10 10 of 20 Part A A positive point charge Q is fixed on a very large horizontal frictionless tabletop. A second positive point charge q is released from rest near the stationary charge and is free to move. Which statement best describes the electric force on q after it is released? O Its force will be greatest just after it is released. O As it moves farther and farther from Q. its force will decrease. O As it moves farther and farther from Q, its speed will increase. O As it moves farther and farther from Q, its electric force will not change. O Its electric force is zero just after it is released.Please answer. Thanks!Resources LX Give U A particle that carries a net charge of –77.8 µC is held in a constant electric field that is uniform over the entire region. The electric field vector is oriented 25.2° clockwise from the vertical axis, as shown in the figure. If the magnitude of the electric field is 9.82 N/C, how much work is done by the electric field as the particle is made to move a distance of d = 0.156 m straight up? d 25.2 work: J What is the potential difference AV between the particle's initial and final positions? AV = V
- In an inkjet printer, letters and images are created by squirting drops of ink horizontally at a sheet of paper from a rapidly moving nozzle. The pattern on the paper is controlled by an electrostatic valve that determines at each nozzle position whether ink is squirted onto the paper or not. Figure 9 Do 163 Ē T 1 of 1 The ink drops have a mass m = 1.00×10-11 kg each and leave the nozzle and travel horizontally toward the paper at velocity = 24.0 m/s. The drops pass through a charging unit that gives each drop a positive charge q by causing it to lose some electrons. The drops then pass between parallel deflecting plates of length Do = 1.50 cm, where there is a uniform vertical electric field with magnitude E= 8.15x104 N/C. (Figure 1) Part A If a drop is to be deflected a distance d = 0.250 mm by the time it reaches the end of the deflection plate, what magnitude of charge q must be given to the drop? Assume that the density of the ink drop is 1000 kg/m³, and ignore the effects of…Three charges q1 = +100µC, q2 = -50µC,and q3 = +60µC are set on each corner of an equilateral triangle of side 1 meter.
