Question

Three charges are fixed in the x?y plane as follows: 1.5 nC at the origin (0, 0); 2.4 nC at (0.75m , 0); –1.9 nC nC at (0, 1.50 m ).

Part A

Find the force acting on the charge at the origin.

Express your answers using two significant figures. Enter the x and y components of the force separated by a comma.

Answer 1

F = k q₁ q₂ / r²

F(x) = -1.5*2.4*9*10^-9*10^-18 / 0.75² = -5.76*10^-8

^{F(y) =} 1.5*1.9*9*10^-9*10^-18 / 1.5² = 1.14*10^-8
