A positive charge of 3.0mu * C is pulled on by two negative charges. As shown in Figure 16, one negative charge - 2.0mu * C , is 0.050 m to the west, and the other, -4.0 mu C. , is 0.030 m to the cast. What net force is exerted on the positive charge ?

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .
