32. Which property of object is responsible for the Gravitational force.
33. How much times is the strong nuclear force stronger then weak nuclear force ?
A. \(10^{13}\)
B. \(10^{2}\)
C. \(10^{-13}\)
D. \(10^{-2}\)
Answer : Option A
Explanation :
\(\frac{Strong\ nuclear\ force}{Electromagnatic\ force}=\frac{1}{10^{-2}}=10^{2}\)
34. How much times is the strong nuclear force stronger then electromagnetic force ?
A. \(10^{13}\)
B. \(10^{2}\)
C. \(10^{-13}\)
D. \(10^{-2}\)
Answer : Option B
Explanation :
\(\frac{Strong\ nuclear\ force}{Weak\ nuclear\ force}=\frac{1}{10^{-13}}=10^{13}\)
35. How much times is the electromagnetic force stronger then Gravitational force
A. \(10^{13}\)
B. \(10^{-13}\)
C. \(10^{36}\)
D. \(10^{-36}\)
Answer : Option C
Explanation :
\(\frac{Electronmagnetic\ force}{Gravational\ force}=\frac{10^{-2}}{10^{-38}}=10^{36}\)
