The sum of two forces is 18 N and resultant whose direciton is at right angles to the smaller force is 12 N. the magnitude of the two forces are

A

`[in_(0]=[M^(-1)L^(-3)T^(2)A]`

B

`[in_(0)]=[M^(-1)L^(-3)T^(4)A^(2)]`

C

`[in_(0)]=[M^(-1)L^(2)T^(-1)A^(-2)]`

D

`[in_(0)]=[M^(-1)L^(2)T^(-1)A]`

Text Solution

Verified by Experts

The correct Answer is:
B
`F=(1)/(4pi in_(0))(q_(1)q_(2))/r^(2)rArr [MLT^(-2)]=[1/in_(0)] (A^(2)T^(2))/L^(2)`
`rArr [epsilon_(0)]=[M^(-1)L^(-3)T^(4)A^(2)]`
