Chemotherapy is a cancer treatment that uses drugs to kill cancer cells. However, it is problematic, because the drugs also kill every healthy cell that they contact. How could nanotechnology best be used to improve the treatment of cancer with chemotherapy?

A: A nanometer-size carrier could be designed to bring the chemotherapy drugs only to cancer cells.
B: A nano carbon wire could be designed that would aid in the manufacture of chemotherapy drugs.
C: A quantum dot could be used to watch where the chemotherapy drugs go in the body.
D: Biomaterials could be made that would allow for cell growth within the cancer cells so that they are easier to find.

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
