A uniform electric field points midway between the positive x and y axies. Its strength is 100Volts/m. A -50nC charge is placed at the position ( 2m, 3m ) and fixed in place. What are the components of the total electric field at the location ( 6m, 6m)?
Find the location of the point where the total electric field is zero.
Illustrate what is its average acceleration during a stop from that velocity? Express your answer in m/s2. Consider the car's initial velocity to be a positive quantity.
Iced tea is made by adding ice to 2.4 kg of hot tea, initially at 70?C. How many kg of ice, initially at 0?C, are required to bring the mixture to 10?C? (Lf = 3.33×105 J/kg, cw = 4,186 J/kg•? C)
