Hi, need help with the physics question. I have attached the screenshot below. Please give the correct answer. Thank you for the help.

The drawing shows an equilateral triangle, each side of which has a length of 4.67 cm. Point charges are fixed to each corner, as shown. The 4.00 JC charge experiences a net force due to the charges qA and qB. This net force points vertically downward and has a magnitude of 625 N. Determine (a) charge qA, (b) charge qB. +4.00 uC 4A (a) Number i Units (b) Number i Units V No units m m/s eTextbook and Media m/s^2 kg Save for Later N Attempts: 0 of 3 used Submit Answer Using multiple attempts will impact your score.

The capacitor is 2.00 cm long, and its plates are separated by 0.150 cm. Assume that the electric field between the plates is uniform everywhere and find its magnitude. 2.00 cm + + + + + 0.150 cm - Number Units V N N/C
