A magnetic needle free to rotate in a fixed vertical plane stays in a direction making an angle of `60^@` with the horizontal. If the dip at that plane is `37^@`, find the angle of the fixed vertical plane with the meridian.

A magnetic needle suspended in a vertical plane at 30^@ from the magnetic meridian makes an angle of 45^@ with the horizontal. Find the true angle of dip.

A magnetic needle is free to rotate in a vertical plane which makes an angle of 60^@ with the magnetic meridian. If the needle stays in a direction making an angle of tan^-1(2//sqrt3) with the horizontal, what would be the true dip at that place?

A magnetic needle is free to rotate in a vertical plance which makes an angle of 60^@ with the magnetic meridian. If the needle stays in a direction making an angle of tan^(-1) (2sqrt(3)) with the horizontal, what would be the dip at that place?

A magnetic needle is free to rotate in a vertical plance which makes an angle of 60^@ with the magnetic meridian. If the needle stays in a direction making an angle of tan^(-1) (2sqrt(3)) with the horizontal, what would be the dip at that place?

A magnetic needle is free to rotate in a vertical plance which makes an angle of 60^@ with the magnetic meridian. If the needle stays in a direction making an angle of tan^(-1) (2sqrt(3)) with the horizontal, what would be the dip at that place?

At 52^@ from the magnetic meridian, a magnetic needle in a vertical plane makes an angle of 45^@ with the horizontal plane. Find the actual angle fo dip at that place.
