Question

1./ The upward net force on the space shuttle at launch is 10,000,000 N. What is the least amount of charge you could move from its nose to the launch pad, 60 m below, and thereby prevent it from lifting off

Answer 1

Answer:

 $Q=2C$

Explanation:

From the question we are told that:

Force $F=10000000N$

Distance $d=60m$

Where

 $Q_1=Q_2$

Generally the equation for Force is mathematically given by

 $F=\frac{KQ^2}{r^2}$

Where

 $K=9*10^9$

Therefore

 $Q^2=\frac{Fr^2}{K}$

 $Q^2=\frac{10000000*60^2}{98*10^9}$

 $Q=\sqrt{\frac{10000000*60^2}{9*10^9}}$

 $Q=2C$
