When performing an. experiment similar to millikan's oil drop, a student measured the following load magnitudes: 3.26x10 ^-19 c 5.09x10 ^-19 c 1.53x10 ^-19 c 6.39x10 ^-19 c 4.66x10 ^-19 c i used these measurements to find the charge on the electron

Explanation:

We put the charges in the ascending order as follows

1.53 P

3.26 P

4.66 P

5.09 P

6.39 P

where P is equal to 10⁻¹⁹

we round off given charges as follows

1.53 P → 1.6 P

3.26 P → 3.2 P

4.66 P → 4.8 P

5.09 P → 4.8 P

6.39 P → 6.4 P

We see that 2 nd to 4 th charges are integral multiples of first charge . That means these charges are supposed to be made of combination of first charge . So first charge appears to be minimum possible charge .

Hence this charge may exist on single electron.
