2C. Two horizontal squares metal plates, with a side of 10 cm, are placed horizontally and parallel one on top of the other at a distance of 1 cm. They acquire opposite charges of equal absolute value price, so that there is a gap between them to have a homogeneous electric field of 2x103 N/C down direction. A particle of mass 2x10-16 Kg with a positive charge of 1x106 C leaves the center of of negative bottom plate with an initial velocity of measure 1x105 m/s at an angle of 37° with the horizontal. Where will it hit, relative to the starting point? (Consider whether gravity can be ignored.) E ++ + + ++++ + F

A point charge of -3.80 µC is located in the center of a spherical cavity of radius 6.50 cm inside an insulating charged solid. The charge density in the solid is +8.70 x 10-4 C/m³. Calculate the magnitude of electric field inside the solid at a distance of 9.50 cm from the center of the cavity. Answer: ✓ Choose... MN/C (mega N/C) kN/C N/C
