Which is a pair of geometrical isomers ?

are-

Assuming earth to be a sphere of a uniform density, what is value of gravitational acceleration. in mine 100 km below the earth surface .... ms^-2

The two optical isomers given below are

Number of stereoisomers of the given compound is -

The given pair is

If the mass of earth is 80 times of that of a planet and diameter is double that of planet and  'g' on the earth is 9.8 ms², then the value of ' g ' on that planet is ….

If the relation between subnormal 'SN' and subtangent 'ST' at any point on the curve by  is  then 

For such questions, we should know the formulas of subnormal and subtangent.

If the radius of earth is R then height 'h ' at which value of ' g' becomes one - fourth is

An object weights 72 N on the earth. Its weight at a height R/2 from earth is ……N

If mass of a body is M on the earth surface, than the mass of the same body on the moont surfae is

If the density of small planet is that of the same as that of the earth while the radius of the planet is 0.2 times that of lhe earth, the gravitational acceleration on the surface of the planet is……

The depth of at which the value of acceleration due to gravity becomes 1/n the time the value of at the surface is (R= radius of earth)

The moon's radius is 1/4 that of earth and its mass is 1/80 times that of the earth. If g  represents the acceleration due to gravity on the surface of earth, that on the surface of the moon is

The length of the tangent of the curves  is

For such questions, we should know the properties of trignometric functions and their different formulas.

If earth rotates faster than its present speed the weight of an object will.
