Two particles of equal mass m and charge...

Two particles of equal mass m and charge t are placed at a distance 16 cm. They do no experience any force. The value of `q/m` is……..

A

1

B

`sqrt(4piepsilon_(0)G)`

C

`sqrt((piepsilon_(0))/G)`

D

`sqrt((G)/(4piepsilon_(0))`

Text Solution

Verified by Experts

The correct Answer is:
B
Weight =Coulomb force
`(Gm^(2))/(16 xx 10^(-2))^(2) = (kq^(2))/(16 xx 10^(-2))^(2)`
`therefore q/m = sqrt(G/k) = sqrt(4piepsilon_(0)G) [therefore k =1/(4piepsilon_(0))]`
