Question

The correct value of charge to mass ratio of an electron is:

• A. $1.7588\times {10}^{11}$ C/g
• B. $1.7588\times {10}^8$ C/g
• C. $1.7588\times {10}^8$ C/kg
• D. $1.7588\times {10}^9$ C/g

Answer 1

The correct option is B $1.7588\times {10}^8$ C/g

charge to mass ratio of a electron was discovered by Thomson and it has a value of $1.7588\times {10}^{11}$ C/kg or $1.7588\times {10}^8$ C/g.
