A particle that carries a net charge of -77.8 /C is held in a constant electric field that is uniform over the entire region. The electric field vector is oriented 55.2' clockwise from the vertical axis, as shown in the figure. If the magnitude of the electric field is 7.32 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 55.20 work: What is the potential difference AV between the particle's initial and final positions? AV = VTwo plates separated by a distance d' = 15.3 mm are charged to a potential difference V : 125 V. A constant force F = 9.31 N pushes a 3.3' mC charge from the positively charged plate to the negatively charged plate. Calculate the change in the kinetic energy AK, potential energjg,Ir AU, and total energyr 33E of the charge as it travels from one plate In the ether. Assume the initial speed of the charge is U. ++++++++++++++| y In the region shown in the image, there is a uniform electric eld of magnitude 30.5 NIC which points in the positive ydirection. Points 2, 3, and 4 are all 0.245 m away from point 1, and the angle ti} 2 311. Calculate the following potential dierences If: P}. where i and j indicate the numbered points. H Three point charges, @1 = 15.4 JC, Q2 = -33.6 JC, and Q3 = 57.3 pC, are arranged as shown in the figure. The + A lengths y and x both equal 80.1 cm. Calculate the electric potential I' at point A. V = V - + Q3 XIn the image are two point charges, Q1 = -90.0 x 10- C and (2 = 40.0 x 10- C, separated by a distance d = 0.300 m. Calculate the potential at point A positioned d2 = 0.120 m to the left of Q1 . A + potential at point A = V
