Question 1 (1 point)
Enrico says that positive charge is created when you rub a glass rod with silk, and that negative charge is simply the absence of positive charge. Rosetta says that negative charge is created and that positive charge is the absence of positive charge. (She has heard that Ben Franklin should have reversed the signs he associated with the charges.) Which one, if either, is correct?
Question 1 options: 1) Enrico, because there really is only one kind of charge. 2) Rosetta, because there really is only one kind of charge. 3) Neither: although no charge is present originally, both types of charge are created through friction. 4) Both: only one type of charge is created by friction at any one time. 5) Neither: both negative and positive charge are present simultaneously in all solid materials on Earth.
Question 2 (1 point)
A particle (m = 50 g, q = 5.0 mC) is released from rest when it is 50 cm from a second particle (Q = -20 mC). Determine the magnitude of the initial acceleration of the 50-g particle.
Question 2 options: 1) 54 m/s2 2) 90 m/s2 3) 72 m/s2 4) 65 m/s2 5) 36 m/s2
Question 3 (1 point)
Two charged particles, Q1 and Q2, are a distance r apart with Q2 = 5Q1. Compare the forces they exert on one another when F1 is the force Q2 exerts on Q1 and F2 is the force Q1 exerts on Q2.
Question 3 options: 1) F2 = 5F1. 2) F2 = -5F1. 3) F2 = F1. 4) F2 = -F1. 5) 5F2 = F1.
Question 4 (1 point)
Each of two small non-conducting spheres is charged positively, the combined charge being 40 mC. When the two spheres are 50 cm apart, each sphere is repelled from the other by a force of magnitude 2.0 N. Determine the magnitude of the smaller of the two charges.
Question 4 options: 1) 1.4 mC 2) 1.1 mC 3) 2.0 mC 4) 3.3 mC 5) 17 mC
Question 5 (1 point)
A uniformly charged rod (length = 2.0 m, charge per unit

...In re Sir Dinshaw Maneckjee Petit Bari AIR 1927 Bom. 371 Marten, C.J. – For the financial year 1925-26, the assessee Sir Dinshaw Petit has been assessed for super-tax on an aggregate income of Rs. 11,35,302 arising in the previous year. Of this sum he objects to Rs. 3,90,804 made up of two sums of Rs.2,76,800 and Rs. 1,14,004, the former of which arises from Government and other fixed interest bearing funds, and the latter from dividends in companies. Nothing appears to turn on this distinction, and I shall accordingly ignore it. Admittedly the assessee is the legal owner of most of these funds in the sense that they stand in his name and the interest and dividends are paid to him direct. Admittedly as regards the rest the apparent legal owners are his nominees and he receives the interest and dividends. Admittedly he has retained all the above interest and dividends and applied the same to his own use. But he contends that he is only a trustee for certain family companies which he has formed: that the interest and dividends are theirs and not his: that he has credited them in account, and that though he has had the benefit of them in specie this is because the family companies have lent him these moneys at interest which he has credited to them in account although he has not actually paid the interest in cash. He says that the family companies are under no obligation to declare a dividend, and are entitled to lend out their income in this way, even though it results over...
