A Martian leaves Mars in a spaceship that is heading to Venus. On the way, the spaceship passes earth with a speed v = 0.86c relative to it. Assume that the three planets do not move relative to each other during the trip. The distance between Mars and Venus is 1.20 × 1011 m, as measured by a person on earth.
(a) What does the Martian measure for the distance between Mars and Venus?
(b) What is the time of the trip (in seconds) as measured by the Martian?
An infinite non conducting sheet has a surface charge density σ = +5.80 pC/m2. (a) How much work is completed by electric field because of the sheet if a particle of charge q = +1.60 × 10-19 C is moved from the sheet to a point P at distance d = 3.56..
