You travel in your ship white star one at a constant speed of v 0.96*c to the nearby star proxima centauri, located 4.2 light years away from earth. a. from your point of view in the ship, how far is the star from the earth? b. if your mass is 68 kg, what is your kinetic energy while moving with the ship? c. how long does the journey take, according to clocks on your ship? d. h e. you have a twin back on earth that was the same ag ow long does the journey take, according to your friends back home on earth? e as you were when you left. when you travel back to earth who is older and by how much?

B, if it was a lower watt she could put it in for her normal time and not burn it

Answer: a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same sign as the  -4.0  µc charge.======electricstatic force between two point charges  is given by    where k is coulomb's constant,  8.99×10⁹  n·m²/c², q₁ and q₂ are the point charges, and r is the distance between the two point charges.assign positive to q₁let q₁ =  6.0 µc, q₂ = -4.0  µc, q₀ represent the charge at the origin, and q₃ represent this new charge to place.the charge at the origin q₀ would experience the following force f₀₁ from q₁, with r = 6.0 m (note that 1  µc = 10⁻⁶ c)    the force from q₂    the force from q₃    the net force on the origin charge, q₀, has to be zero for no electrostatic forcehaving an equation where k and q₀ can be divided out of the equation will allow us to solve for q₃    isolating:     a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same as the  -4.0  µc charge
