The time of vibration of a dip needle in the vertical plane is 3 sec the magnetic needle is made to vibrate in the horizontal plane, the time of vibration is `3sqrt2 s`. Then angle of dip will be-

The time of vibration of a dip needle vibration in the vertical plane in the magnetic needle is made to vibrate in the horizontal plane, the time of vibration is 3sqrt2 s . Then angle of dip will be-

A dip needle vibrates in the vertical plane perpendicular to the magnetic meridian. The time period of vibration is found to be 2 sec. The same needle is then allowed to vibrate in the horizontal plane and the time period is again found to be 2 seconds. Then the angle of dip is

The vertical plane in which magnetic needle lies at a place is called______

A dip needle vibrates in a vertical plane with time period of 3 second . The same needle is suspended horizontally and made to vibrate is a horizontal plane . The time period is again 3 sec. The angle of dip at that place is .

A dip needle in a plane perpendicular to magnetic meridian will remain

If a dip needle is suspended at an angle 30° to the magnetic meridian, it makes an angle of 45^@ with the horizontal. The real dip is

A thin magnetic needle oscillates in a horizontal plane with a period T. It is broken into n equals parts. The time period of each part will be
