Assertion : Four point masses each of mass `m` are placed at points 1, 2, 3 and 6 of a regular hexagon of side a. Then the gravitational field at the centre of hexagon is `(Gm)/(a^(2))`

Reason : The field strength due to masses at 3 and 6 are cancelled out.

A

If both Assertin and Reason are correct and Reason is the correct explanation of Assertion

B

If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion

C

If Assertion is true but Reason is false

D

If Assertion is false but Reason is true

Text Solution

Verified by Experts

The correct Answer is:
D

Field strengths due to masses at 1 and 2 are acting at `60^(@)`.
Therefore, resultant is `(sqrt(3)Gm)/(a^(2))`
