An insurance company estimates that the probability that a person’s car will be destroyed and need to be replaced in any given year is 0.03. The insurance company charges $2000 for the insurance policy, and if your car is destroyed, they will give you $25000 to buy a replacement car. Let X be the net earnings for the insurance company from one insurance policy. What is the expected net earnings for this insurance company? On average, will the insurance company tend to earn money or lose money?

Consider a long line of charge with linear charge density lambda = 4 micro C/m and a point charge q = −2 micro C with mass m = 0.1 kg at coordinate 2,3 . The point charge is launched from (2,3) with v= 2000 m/s at an angle of 20° with respect to the x-axis. Find the velocity of the point charge when its x-coordinate is 5.( wire goes to positive infinity Y axis)

2. a) What do you mean by investment? Why are
financial investments not considered as investment in
Economics?
b) Briefly describe the determining factors of investment
spending.
c) Cost for an investment project is Tk. 2000. Expected yields of
the projects are Tk.1000 in the current year and Tk. 1150 in the
next year. If the market interest rate is 10%, will it be amenable
to undertake the project. How would your answer change if interest
rate rises to 15%?

Suppose that a company has a Monopoly in the production of keyboards. Market research shows that it faces a market demand function given by
P (q) = 100 ? (1/4)Q.
Its cost function is
C(Q) = 2000 + 2Q.
a. What would the price and quantity be in this market be if the company behaved as in perfect competition?
b. What is the consumer surplus in the case of perfect competition? Why is it higher than if it was a monopoly case? What is the social cost of monopoly?
