Tidal forces around Schwarzschild black hole in cloud of strings and quintessence

Abstract

AbstractWe study the tidal forces and their effect in Schwarzschild black hole surrounded with clouds of strings and quintessence. Two horizons are present for this black hole and the event horizon shrinks on increasing the values of both, the string cloud and quintessence parameters. Tidal forces in radial as well as angular directions are independent of string cloud parameter a. Geodesic deviation equations are devised and solved for this BH metric. For numerical representation of the solutions of geodesic deviation equations two different initial conditions have been applied. Results are compared with that of Schwarzschild black hole metric.
